    Breast carcinoma is the most common cancer in women, the second leading cause of cancer-related mortality in women, and the leading cause of death from cancer in women between the ages of 40 and 44. While cystic breast disease is the most frequent cause of benign breast masses, intracystic breast cancers are rare. We present a case of a postmenopausal woman with a large cystic breast carcinoma with its interesting radiologic and cytopathologic findings and review the literature.

    Breast cancer screening is known to reduce breast cancer mortality. A high breast density may affect this reduction. We assessed the effect of screening on breast cancer mortality in women with dense and fatty breasts separately. Analyses were performed within the Nijmegen (Dutch) screening programme (1975-2008), which invites women (aged 50-74 years) biennially. Performance measures were determined. Furthermore, a case-control study was performed for women having dense and women having fatty breasts. Breast density was assessed visually with a dichotomized Wolfe scale. Breast density data were available for cases. The prevalence of dense breasts among controls was estimated with age-specific rates from the general population. Sensitivity analyses were performed on these estimates. Screening performance was better in the fatty than in the dense group (sensitivity 75.7% vs 57.8%). The mortality reduction appeared to be smaller for women with dense breasts, with an odds ratio (OR) of 0.87 (95% CI 0.52-1.45) in the dense and 0.59 (95% CI 0.44-0.79) in the fatty group. We can conclude that high density results in lower screening performance and appears to be associated with a smaller mortality reduction. Breast density is thus a likely candidate for risk-stratified screening. More research is needed on the association between density and screening harms. © 2016 UICC.

    Full Text Available Background: Sexual dysfunction in breast cancer patients is considered as a common and distressing problem. Considering the increasing number of breast cancer survivors living for longer periods of time with the disease and the importance of their quality of life, we conducted the present study to compare the sexual functioning in breast cancer patients with their healthy counterparts.Methods: In this case-control study, breast cancer patients who completed their treatment protocol and were followed up for at least six months were included. The controls were healthy women with normal clinical breast examinations. All subjects filled-in the Persian version of Female Sexual Function Index questionnaire.Results: A total of 165 subjects including 71 breast cancer patients and 94 healthy women were studied. The frequency of sexual dysfunction in cases and controls was 52.6% and 47.4%, respectively (P = 0.09. There were no significant differences between the two groups regarding domain scores, except for vaginal lubrication (P = 0.045. Logistic regression analysis indicated that significant determinants of sexual dysfunction in breast cancer group was patients' age (OR = 4.0, 95%CI: 1.3 – 11.5, P = 0.01 and age of the spouse (OR= 9.8, 95% CI: 1.8-51.9, P= 0.007, while in controls, only emotional relationship with the husband was the significant predictive factor (OR = 6.3, 95%CI: 1.9 – 20.5, P = 0.002.Conclusions: Our findings indicated that sexual dysfunction is prevalent in Iranian women regardless of their physical health status. The frequency of vaginal dryness in breast cancer patients was significantly higher than controls. Age of the patient and the spouse (>40 were the only significant predictors of sexual dysfunction among women with breast cancer. Preventive strategies, sexual education and access to effective treatment should be planned in supportive care of breast cancer patients.

    Full Text Available Prior pregnancy is known to protect against development of breast cancer. Recent studies have demonstrated that pregnancy has the capacity to establish small numbers of immunologically active fetal-derived cells in the mother, a phenomenon known as fetal microchimerism (FMc. We asked whether presence of FMc, routinely acquired during pregnancy, is a protective factor for breast cancer.DNA extracts from peripheral blood specimens were obtained from a population-based case-control study of risk factors for breast cancer in women 21 to 45 years old. Specimens were tested with quantitative PCR for presence and concentrations of male DNA presumed to derive from prior pregnancies with a male fetus. Odds ratios (OR and 95% confidence intervals (CI were estimated with consideration of multiple established reproductive and environmental risk factors for breast cancer. FMc results were generated on 99 parous women, 54 with primary invasive breast cancer and 45 general population controls. FMc prevalence was 56% (25/45 and 26% (14/54 in controls and cases, respectively. Women harboring FMc were less likely to have had breast cancer (OR = 0.29, 95% CI 0.11-0.83; p = 0.02, adjusting for age, number of children, birth of a son, history of miscarriage, and total DNA tested. In addition, FMc concentrations were higher in controls versus cases (p = 0.01. Median concentrations were 2 (0-78 and 0 (0-374 fetal genomes/10(6 maternal genomes in controls and cases, respectively.Results suggest that the enigma of why some parous women are not afforded protection from breast cancer by pregnancy might in part be explained by differences in FMc. Mechanistic studies of FMc-derived protection against breast cancer are warranted.

    Breast cancer is diagnosed in pregnant women during pregnancy or the first year after childbirth, and is the second leading cause of death among women of reproductive age. We don't know the frequency of this disease or the characteristics of the women affected at the Juarez Hospital of Mexico. This paper analyzed the cases of pregnant women diagnosed with breast cancer treated in the Oncology Department over a period of 10 years (1990-2000). We performed a retrospective descriptive study of pregnant women diagnosed with breast cancer, treated at the hospital. Of the cases found, the following indicators were studied: maternal age, type of cancer, weeks of gestation at the time of diagnosis, resolution of pregnancy and perinatal outcome, and treatment monitoring. Descriptive statistics were performed using measures of central tendency and dispersion. There were 14 cases of pregnant women with breast cancer. The mean age of patients was 28 years, with a mean of 23 weeks gestation at diagnosis. The resolution of pregnancy was favorable in 73% of cases. 78.6% of the patients were treated, 72.7% had follow-up for 2 years that found 62.5% of patients without tumor activity. The frequency of pregnant women with breast cancer is low, affecting young people. The choice of treatment allowed the resolution of pregnancy and survival of women without tumor activity.

    Full Text Available Background: Breast cancer is second most important cancer among Indian women. Although risk factors are not much prevalent as in western countries, incidence rate is increasing in India. The study was undertaken to study various risk factors associated with breast cancer. Methods: A hospital based group matched case control study was undertaken to identify risk factors. The study consisted of 105 hospitalized cases confirmed on histopathology and 210 group matched controls selected from urban field practice area, Sadar, without any malignancy. Bivariate analyses included odds ratio (OR, 95% confidence interval (CI for odds ratio. Results: Earlier age at menarche ≤ 12 years of age, late age at first full term delivery, nulliparity, Lack of breast-feeding were found to be significantly associated with the risk of breast cancer in both pre menopausal & post menopausal women while age at menopause at or after 50 years was significantly associated with the risk in post menopausal women. Conclusions: Study suggests that the changes in menstrual and reproductive patterns among women i.e. early age at menarche and late age at first childbirth and some environmental factors in Central India may have contributed to the increase in breast cancer risk, particularly among younger women.

    The aim of the present study was to examine if certain aspects of a woman's experience of abortion might be associated with the risk of breast cancer. The case-control study was conducted in Kragujevac (Serbia) during the period 2004-2005. The case group (191 women) consisted of patients with newly diagnosed first primary breast cancer, which was histologically confirmed. The control group (191 women), individually matched by age (± 2 years), hospital admittance and place of residence (rural/urban) to the respective cases, was selected from female patients admitted for other diseases. The analysis was restricted to parous women (168 cases and 171 controls). Breast cancer risk was reduced among women who had a history of any abortion (adjusted OR, 0.46; 95% CI, 0.24-0.88). The protective effect was found for both induced abortion (adjusted OR, 0.47; 95% CI, 0.25-0.90) and spontaneous abortion (adjusted OR, 0.31; 95% CI, 0.10-0.98). It seems that these associations did not depend on the number of abortions, age at first abortion, or gestational age at first aborted pregnancy. Our study suggests that even short pregnancies ending in abortion add to the protection against breast cancer.

    OBJECTIVE--To investigate whether breast feeding is related to subsequent risk of breast cancer. DESIGN--Population based case-control study designed primarily to investigate the relation between oral contraceptives and risk of breast cancer; data obtained from questionnaires administered by interviewers, general practitioner notes, and family planning clinic records. SETTING--11 health regions in Britain. SUBJECTS--Women diagnosed with breast cancer before age 36 living in the defined study areas. One control per case, matched for age, was selected from the list of the case's general practitioner. 755 case-control pairs were interviewed. MAIN OUTCOME MEASURES--Duration of breast feeding each liveborn infant; timing of return of menses; hormone use; other risk factors for breast cancer. RESULTS--Risk of breast cancer fell with increasing duration of breast feeding (relative risk = 0.94 per three months' breast feeding; test for trend p = 0.026) and with number of babies breast fed (relative risk = 0.86; test for trend, p = 0.017). Breast feeding each baby for longer than three months conferred no additional benefit. Breast feeding was more strongly negatively associated with risk of breast cancer than duration of postpartum amenorrhoea (chi 2 test for trend, p = 0.69). Hormonal suppression of lactation was unrelated to risk of breast cancer (relative risk = 0.96 per episode of suppressed lactation; test for trend, p = 0.72). CONCLUSIONS--These results suggest that breast feeding protects against the development of breast cancer in young women. PMID:8343660

    A case-control study was conducted in Miyagi and Gunma prefectures, Japan, to evaluate the effectiveness of breast cancer screening by clinical breast examination (CBE) alone in reducing breast cancer mortality. Case subjects, who were female and had died of breast cancer, were collected from residential registry files and medical records. Control subjects matched in sex, age and residence were randomly selected from residential registry files. The screening histories during 5 years prior to the cases having been diagnosed as breast cancer were surveyed using the examinee files of the screening facilities. Finally, the data of 93 cases and 375 controls were analyzed. The odds ratio (OR) of breast cancer death for participating in screening at least once during 5 years was 0.93 (95% confidence interval (95% CI) 0.48-1.79). The cases were more symptomatic than the controls when screened. If the participants who had had symptoms in their breasts were classified as not screened, the OR decreased to 0.56 (95% CI 0.27-1.18). The case control study suggests that the current screening modality (CBE) lacks effectiveness (OR = 0.93), although it might be effective for an asymptomatic population (OR = 0.56). The number of cases was small, and a larger case-control study is desirable to define whether CBE is effective or not. However, it is necessary to consider the introduction of mammographic screening to reduce breast cancer mortality in Japan.

    Recurrence that poses the biggest problem after breast-conserving surgery is local recurrence. Particularly, in the case of inflammatory breast recurrence which is rare but has a specific pathologic nature, it is important to elucidate the pathology and risk factors and to consider appropriate countermeasures. In the present study, we classified 133 cases of recurrence following breast-conserving surgery, collected from 18 key hospitals/institutes in Japan. Recurrence types were divided into three groups, namely, inflammatory breast recurrence, noninflammatory breast recurrence and distant metastasis only, and the risk factors involved in recurrence were investigated by the case control study allotting 2 controls to each case. The study population consisted of 9 cases of the inflammatory type, 64 cases of the noninflammatory type and 60 cases of distant metastasis. The significant risk factor for inflammatory breast recurrence was positive lymph node metastasis, which was significantly more frequent in lymphatic invasion-positive cases unlike in the distant metastasis group. The positive surgical margin and nonradiation therapy which have been shown to be significant risk factors for noninflammatory breast recurrence were entirely unrelated with inflammatory breast recurrence. In addition, the inflammatory-type recurrence time was as short as about 12 months irrespective of whether radiation therapy was performed or not. The inflammatory type was accompanied with local wide extension (cancerous embolus of the dermal lymphatic vessels), and distant metastasis (lymphangitis carcinomatosa) at the time of recurrence, and further surgery was impossible in most cases, with a significantly poorer prognosis than the other recurrence types. These findings suggest that this recurrence corresponds to the so-called 'occult' case of primary inflammatory breast carcinoma. We think it important to predict this recurrence by close pathological examination, particularly in patients

    The aim of this study is to detect the accumulation status of organochlorine pesticides in breast cancer patients and to explore the relationship between organochlorine pesticides contamination and breast cancer development. We conducted a hospital-based case-control study in 56 patients with breast cancer and 46 patients with benign breast disease. We detected the accumulation level of several organochlorine pesticides products (β-hexachlorocyclohexane, γ-hexachlorocyclohexane, polychlorinated biphenyls-28, polychlorinated biphenyls-52, pentachlorothioanisole, and pp'-dichlorodiphenyldichloroethane) in breast adipose tissues of all 102 patients using gas chromatography. Thereafter, we examined the expression status of estrogen receptor, progesterone receptor, human epidermal growth factor receptor-2 (HER2), and Ki-67 in 56 breast cancer cases by immunohistochemistry. In addition, we analyzed the risk of breast cancer in those patients with organochlorine pesticides contamination using a logistic regression model. Our data showed that breast cancer patients suffered high accumulation levels of pp'-dichlorodiphenyldichloroethane and polychlorinated biphenyls-52. However, the concentrations of pp'-dichlorodiphenyldichloroethane and polychlorinated biphenyls-52 were not related to clinicopathologic parameters of breast cancer. Further logistic regression analysis showed polychlorinated biphenyls-52 and pp'-dichlorodiphenyldichloroethane were risk factors for breast cancer. Our results provide new evidence on etiology of breast cancer.

    In England, a national breast screening programme (NHSBSP) has been in place since 1988, and assessment of its impact on breast cancer incidence and mortality is essential to ensure that the programme is indeed doing more good than harm. This article describes large observation studies designed to estimate the effects of the current programme in terms of the benefits on breast cancer incidence and mortality and detrimental effect in terms of overdiagnosis. The case-control design of the cervical screening programme evaluation was highly effective in informing policy on screening intervals and age ranges. We propose innovative selection of cases and controls and gathering of additional variables to address new outcomes of interest and develop new methodologies to control for potential sources of bias. Traditional case-control evaluation of breast screening uses women who have died from breast cancer as cases, and women known to be alive at the time of case death as controls. Breast screening histories prior to the cases' date of first diagnosis are compared. If breast screening is preventing mortality from breast cancer, cases will be characterised by a lesser screening history than controls. All deaths and incident cases of primary breast cancer in England within each 2-year study period will be included in this ongoing evaluation. Cases will be age- and area-matched to controls and variables related to cancer treatment and breast tumour pathology will be obtained to investigate the interplay between screening and treatment, and the effect of screening on incidence of advanced stage disease. Screening attendance at other national screening programmes will also be collected to derive superior adjustment for self-selection bias.The study is registered and has received full ethics approval.

    Pregnancy, parity, and circulating steroid hormone levels are associated with risk of breast cancer, but little is known about hormone concentrations during pregnancy and subsequent breast cancer risk. We evaluated early pregnancy (breast cancer risk in a nested case-control study in the Finnish Maternity Cohort. The cohort includes 98% of pregnancies registered in Finland since 1983. Individuals with samples collected in the first pregnancy leading to a live birth were eligible. Breast cancer cases (n = 1,199) were identified through linkage with the Finnish Cancer Registry; 2,281 matched controls were selected using incidence density sampling. ORs were calculated using conditional logistic regression. Hormone concentrations were not associated with breast cancer overall. Estradiol was positively associated with risk of breast cancer diagnosed age breast cancer diagnosed at age ≥40 [4th vs. 1st quartile OR 0.71 (0.51-1.00); Ptrend = 0.02]. Elevated concentrations of the steroid hormones were associated with increased risk of estrogen receptor (ER)- and progesterone receptor (PR)-negative tumors in women age pregnancy steroid hormones and risk of ER(-)/PR(-) breast cancer in women diagnosed age breast cancer diagnosed age ≥40.

    Full Text Available In Albania, breast cancer is an important cause of death among women, with increasing incidence from 65 cases in 1970, to 400 cases in 2007. This is the first study concerning breast cancer risk factors in Albania. We used a population-based case-control study of 948 women with breast cancer compared with 1019 controls recruited from other hospitals through random selection. Early age at menarche was found to be a significantly strong risk factor during the pre- and postmenopausal groups with OR 10.04 and 12.1, respectively. In addition, nulliparity is associated with higher risk while abortion did not indicate any influence in the multivariate model. The findings from this study have shown that reproductive and menstrual variables are significant predictors of breast cancer risk in Albanian women, as seen in studies of other western countries.

    Molecular breast imaging (MBI) is a functional test used for supplemental screening of women with mammographically dense breasts. Additionally, MBI depicts variable levels of background parenchymal uptake (BPU) within nonmalignant, dense fibroglandular tissue. We investigated whether BPU is a risk factor for breast cancer. We conducted a retrospective case-control study of 3027 eligible women who had undergone MBI between February 2004 and February 2014. Sixty-two incident breast cancer cases were identified. A total of 179 controls were matched on age, menopausal status, and MBI year. Two radiologists blinded to case status independently assessed BPU as one of four categories: photopenic, minimal to mild, moderate, or marked. Conditional logistic regression analysis was performed to estimate the associations (OR) of BPU categories (moderate or marked vs. minimal to mild or photopenic) and breast cancer risk, adjusted for other risk factors. The median age was 60.2 years (range 38-86 years) for cases vs. 60.2 years (range 38-88 years) for controls (p = 0.88). Women with moderate or marked BPU had a 3.4-fold (95 % CI 1.6-7.3) and 4.8-fold (95 % CI 2.1-10.8) increased risk of breast cancer, respectively, compared with women with photopenic or minimal to mild BPU, for two radiologists. The results were similar after adjustment for BI-RADS density (OR 3.3 [95 % CI 1.6-7.2] and OR 4.6 [95 % CI 2.1-10.5]) or postmenopausal hormone use (OR 3.6 [95 % CI 1.7-7.7] and OR 5.0 [95 % CI 2.2-11.4]). The association of BPU with breast cancer remained in analyses limited to postmenopausal women only (OR 3.8 [95 % CI 1.5-9.3] and OR 4.1 [95 % CI 1.6-10.2]) and invasive breast cancer cases only (OR 3.6 [95 % CI 1.5-8.8] and OR 4.4 [95 % CI 1.7-11.1]). Variable BPU was observed among women with similar mammographic density; the distribution of BPU categories differed across density categories (p risk factor for breast cancer.

    To determine whether induced abortion (IA) increases breast cancer (BC) risk. A population-based case-control study was performed from Dec, 2000 to November, 2004 in Shanghai, China, where IA could be verified through the family planning network and client medical records. Structured questionnaires were completed by 1,517 cases with primary invasive epithelial breast cancer and 1,573 controls frequency- matched to cases for age group. The information was supplemented and verified by the family planning records. Statistical analysis was conducted with SAS 9.0. After adjusting for potential confounders, induced abortions were not found to be associated with breast cancer with OR=0.94 (95%CI= 0.79-1.11). Compared to parous women without induced abortion, parous women with 3 or more times induced abortion (OR=0.66, 95%CI=0.46 to 0.95) and women with 3 or more times induced abortion after the first live birth (OR=0.66, 95%CI =0.45 to 0.97) showed a lower risk of breast cancer, after adjustment for age, level of education, annual income per capita, age at menarche, menopause, parity times, spontaneous abortion, age at first live birth, breast-feeding, oral contraceptives, hormones drug, breast disease, BMI, drinking alcohol, drinking tea, taking vitamin/calcium tablet, physical activity, vocation, history of breast cancer, eating the bean. The results suggest that a history of induced abortions may not increase the risk of breast cancer.

    Growing evidence suggests that quantitative descriptors of the parenchymal texture patterns hold a valuable role in assessing an individual woman's risk for breast cancer. In this work, we assess the hypothesis that breast cancer risk factors are not uniformly expressed in the breast parenchymal tissue and, therefore, breast-anatomy-weighted parenchymal texture descriptors, where different breasts ROIs have non uniform contributions, may enhance breast cancer risk assessment. To this end, we introduce an automated breast-anatomy-driven methodology which generates a breast atlas, which is then used to produce a weight map that reinforces the contributions of the central and upper-outer breast areas. We incorporate this methodology to our previously validated lattice-based strategy for parenchymal texture analysis. In the framework of a pilot case-control study, including digital mammograms from 424 women, our proposed breast-anatomy-weighted texture descriptors are optimized and evaluated against non weighted texture features, using regression analysis with leave-one-out cross validation. The classification performance is assessed in terms of the area under the curve (AUC) of the receiver operating characteristic. The collective discriminatory capacity of the weighted texture features was maximized (AUC=0.87) when the central breast area was considered more important than the upperouter area, with significant performance improvement (DeLong's test, p-valuebreast-anatomy-driven methodologies have the potential to further upgrade the promising role of parenchymal texture analysis in breast cancer risk assessment and may serve as a reference in the design of future studies towards image-driven personalized recommendations regarding women's cancer risk evaluation.

    Male breast cancer is rare, comprising only 1% of all mammary cancers; invasive ductal carcinoma is by far the commonest subtype in both men and women. Though lobular breast cancer is the second most common subtype seen in women, such cancers are extremely uncommon in men, and this is likely related to the lack of lobular development in the male breast. Thus, due to the rarity of this subtype among breast cancers, compounded by the overall rarity of breast cancer in men, current understanding of the pathogenesis of this disease and its management is largely derived from case series and extrapolation of information from the larger cohort of female patients. This paper provides a systematic review on invasive lobular carcinoma of the male breast in the context of an illustrative case study. A comprehensive analysis of the National Cancer Institute's Surveillance, Epidemiology, and End Results Data 1973-2013 leading to an exploration of the pathogenesis, epidemiology, clinical presentation, diagnosis, tumor characteristics, and management of lobular breast carcinoma in men is also discussed. Lobular subtype of breast cancer remains an enigmatic elusive disease that needs additional research to unravel its overall pathogenesis and molecular profile to provide insight for improved therapeutic management options.

    Canine and human breast cancer share several important clinical and histologic features. A case-control study of nutritional factors and canine breast cancer was conducted at the Veterinary Hospital of the University of Pennsylvania in 1984-1987 by interviewing owners of 150 pet dogs diagnosed with breast cancer, owners of 147 cancer control dogs, and owners of 131 noncancer control dogs. The risk of breast cancer was significantly reduced in dogs spayed at or before 2.5 years of age. Neither a high-fat diet nor obesity 1 year before diagnosis increased the risk of breast cancer according to multiple logistic regression analysis. However, the risk of breast cancer among spayed dogs was significantly reduced in dogs that had been thin at 9-12 months of age (odds ratio (OR) = 0.04 (95% confidence interval (CI) 0.004-0.4) and OR = 0.04 (95% CI 0.004-0.5) for cases vs. cancer controls and cases vs. noncancer controls, respectively, after adjustment for age at spay). Among intact dogs, the risk associated with being thin at 9-12 months of age was reduced, but not significantly so (OR = 0.60 (95% CI 0.2-1.9) and OR = 0.51 (95% CI 0.2-1.4) for the two comparisons, respectively). Results of this study suggest that nutritional factors operating early in life may be of etiologic importance in canine breast cancer.

    Full Text Available Background. Vietnam has a low age-standardized incidence of breast cancer, but the incidence is rising rapidly with economic development. We report data from a matched case-control study of risk factors for breast cancer in the largest cancer hospital in Vietnam. Methods. 492 incident breast cancer cases unselected for family history or age at diagnosis and 1306 control women age 25–75 were recruited from the National Cancer Hospital (BVK, Hanoi. Structured interviews were conducted and pathology data was centrally reported at the National Cancer Hospital of Vietnam, in Hanoi. Results. Our analysis included 294 matched pairs. Mean age at diagnosis was 46.7 years. Lower mean parity, older age at first parity, increasing weight and BMI at age 18, and increasing BMI at diagnosis were positively correlated with breast cancer cases compared to controls. Age at first menarche and duration of breastfeeding were not statistically different between cases and controls. Conclusions. In this study we demonstrate that breast cancer in Vietnam is associated with some but not all of the published risk factors from Western populations. Our data is consistent with other studies of breast cancer in Asian populations.

    Cytomegalo virus is a ubiquitous virus often associated with congenital infections. Some studied have claimed an association between infection with this virus and development of breast cancer. The aim of this prospective research was to study the difference in Cytomegalo virus sero-positivity among patients with breast cancer and benign breast diseases, and thereby to prove any association. This was a hospital based Case-Control study conducted at the General Surgery wards of our hospital, a tertiary level public sector health care institution. This study was done on 130 patients with breast swellings who underwent surgical excision of their lumps over a 1-year period. Patients with histologically proven malignancies were selected as cases while proven benign cases were deemed to be the controls. IgG and IgM antibodies to Cytomegalo virus were checked in the patients from both groups. All of the studied patients turned out to be positive for Immunoglobulin G against Cytomegalo virus while all the patients were found to be negative for Immunoglobulin M. There was no difference in the antibody titers among the benign and malignant cases in the study. Logistic regression calculation was also carried out including the study parameters and other known risk factors. We conclude that there is no association between Cytomegalo virus sero-positivity and breast cancer. Another conclusion is that the studied adult population has been exposed to Cytomegalo virus in some point of their lives. Further studies of a larger magnitude are essential to confirm our results.

    Full Text Available Abstract Background Breast cancer is the most common form of malignancy affecting women worldwide. It is also the leading cancer in females in Cyprus, with approximately 400 new cases diagnosed annually. It is well recognized that genetic variation as well as environmental factors modulate breast cancer risk. The main aim of this study was to assess the strength of associations between recognized risk factors and breast cancer among Cypriot women. This is the first epidemiological investigation on risk factors of breast cancer among the Cypriot female population. Methods We carried out a case-control study, involving 1,109 breast cancer patients and a group of 1,177 controls who were recruited while participating in the National screening programme for breast cancer. Information on demographic characteristics and potential risk factors were collected from both groups during a standardized interview. Logistic regression analysis was used to assess the strength of the association between each risk factor and breast cancer risk, before and after adjusting for the possible confounding effect of other factors. Results In multivariable models, family history of breast cancer (OR 1.64, 95% CI 1.23, 2.19 was the strongest predictor of breast cancer risk in the Cypriot population. Late menarche (OR 0.64, 95% CI 0.45, 0.92 among women reaching menarche after the age of 15 vs. before the age of 12 and breastfeeding (OR 0.74, 95% CI 0.59, 0.92 exhibited a strong protective effect. In the case of breastfeeding, the observed effect appeared stronger than the effect of pregnancy alone. Surprisingly, we also observed an inverse association between hormone replacement therapy (HRT although this may be a product of the retrospective nature of this study. Conclusion Overall the findings of our study corroborate with the results of previous investigations on descriptive epidemiology of risk factors for breast cancer. This investigation provides important background

    Full Text Available Abstract Background Tobacco smoke exposure may be associated with increased breast cancer risk, although the evidence supporting the association is inconclusive. We conducted a case-control study in Delaware, incorporating detailed exposure assessment for active and secondhand smoke at home and in the workplace. Methods Primary invasive breast cancer cases diagnosed among female Delaware residents, ages 40–79, in 2000–2002 were identified through the Delaware cancer registry (n = 287. Delaware drivers license and Health Care Finance Administration records were used to select age frequency-matched controls for women Results A statistically significant increased risk of breast cancer was observed for ever having smoked cigarettes (odds ratio = 1.43, 95% confidence interval = 1.03–1.99. However, there was no evidence of a dose-response relationship between breast cancer risk and total years smoked, cigarettes per day, or pack-years. Neither residential nor workplace secondhand smoke exposure was associated with breast cancer. Recalculations of active smoking risks using a purely unexposed reference group of women who were not exposed to active or secondhand smoking did not indicate increased risks of breast cancer. Conclusion These findings do not support an association between smoking and breast cancer.

    Spatio-ecological study of disease provides a framework to study the interaction of genetic, environmental, social, cultural and behavioural factors on people's health. The occurrence and interaction of these factors are different in different places, giving rise to distinct geographic or spatial variation. Diseases like breast cancer have variation both spatially and temporally. Public health practitioners can use Geographic Information System (GIS) as a visualization tool to effectively present geographic phenomenon and depict it in maps that might remain otherwise undiscovered in tabular form. To demonstrate how GIS can be used to understand and communicate breast cancer data through spatial visualization techniques. (i) To visualize the Spatial Distribution of Breast cancer incidences by a point map. (ii) To visualize the Temporal distribution of breast cancer incidences by thematic maps for the study period of 2007 -2011. Total 1090 breast cancer case records collected for the year 2007-2012 were segregated taluk wise for the 29 taluks and geocoded using the address of the patient, creating a point map. ArcGIS 10.2 software was used to prepare thematic map of breast cancer cases. The taluk wise aggregated breast cancer incidence from the year 2007 to 2011 was then attributed into polygon map representing taluks (Base Map). Natural break data classification technique was used to classify the breast cancer incidence data and breast cancer incidences were classified as low, moderate, high and very high. Spatial distribution of breast cancer incidences using thematic mapping methods high incidences were reported in MY_ T24 (Hunsur), MY_ T25 (KR Nagar), MY_27 (Nanjangud), CH_T1 (Chamrajnagar) and CH-T2 (Gundlupet). Temporal maps prepared for the study from 2007 to 2011 showed that Mysore Taluk had very high Incidence level and the same was observed throughout the study period. The taluks which have high and moderate intensities seem to be fluctuating. However, 25

    Uruguay exhibits one of the highest rates of breast cancer in Latin America, similar to those of developed nations, the reasons for which are not completely understood. In this study we investigated the effect that ancestral background has on breast cancer susceptibility among Uruguayan women. We carried out a case-control study of 328 (164 cases, 164 controls) women enrolled in public hospitals and private clinics across the country. We estimated ancestral proportions using a panel of nuclear and mitochondrial ancestry informative markers (AIMs) and tested their association with breast cancer risk. Nuclear individual ancestry in cases was (mean ± SD) 9.8 ± 7.6% African, 13.2 ± 10.2% Native American and 77.1 ± 13.1% European, and in controls 9.1 ± 7.5% African, 14.7 ± 11.2% Native American and 76.2 ± 14.2% European. There was no evidence of a difference in nuclear or mitochondrial ancestry between cases and controls. However, European mitochondrial haplogroup H was associated with breast cancer (OR = 2.0; 95% CI 1.1, 3.5). We have not found evidence that overall genetic ancestry differs between breast cancer patients and controls in Uruguay but we detected an association of the disease with a European mitochondrial lineage, which warrants further investigation.

    Full Text Available Background: Breast cancer is one of the most prevalent cancers among women and features increasing trends of incidence rates. Worldwide, yearly about 1.67 million of new cases and 522,000 of deaths from breast cancer are registered. The aim of this study was to determine the risk factors of breast cancer in women and to identify high risk groups. Methods: In a case-control study, 170 women with breast cancer who were registered in cancer registration system from 2011 to 2015 at Dezful City, Iran, were compared with 170 healthy women with confirmation of mammography. After age matching of groups, the needed information about risk factors and demographic information including information, educational level, marital status, family history of breast cancer, age at menarche, parity, oral contraceptive use, age at first pregnancy, menopausal status, and age at menopause, breastfeeding, stress, abortion, alcohol use and smoking, hormone therapy and physical activity was collected by a questionnaire. The analysis of collected data was performed by using odds ratio and logistic regression model and SPSS software, version 16 (SPSS, Inc., Chicago, IL, USA. The statistical significance was set at a two-sided p-value of %5. Results: The results of this study showed that, women with the family history [OR: 6.78 (95% CI: 2.15-21.41] and women with the stress history [OR: 4.86 (95% CI: 2.46-9.59] had higher risk of breast canser, while women with the history of having physical activity at least once a week [OR: 0.29 (95% CI: 0.13-0.65] and women with the history breast feeding for 3 to 4 years [OR: 0.36 (95% CI: 0.16-0.81] had lower risk of breast cancer. Conclusion: It is recommended that the mentioned risk factors and protective factors be considered in first and second level (screening of preventive programs.

    Full Text Available Background: Neonatal jaundice, especially breast feeding jaundice is one of the most common causes of neonatal readmission during the first month of life. Breast feeding jaundice may be due to decreased milk intake with dehydration and/or reduced caloric intake.  The aim of this Study was to determine maternal risk factors of breast feeding jaundice in order to prevent it than before.Methods: This case- control study was performed at Bahrami University Hospital, Tehran, Iran and involved 75 term exclusively breast fed newborns admitted for hyperbilirubinemia, with a weight loss greater than 7%, with one positive lab data as: serum Na≥ 150meq/lit, urine specific gravity> 1012, serum urea≥ 40mgr/dl, without assigned cause for hyperbilirubinemia. They were compared with 75 matched controls with weight loss less than 7%, without dehydration and a known cause of hyperbilirubinemia.Results: In comparison with control group, in neonates with breast feeding jaundice, inappropriate feeding practice (P<0.033, delayed onset of lactation (P<0.0001, inverted nipple (P<0.001 were significantly higher. In our study, there was no significant difference between two groups in education level of mother, learning breast feeding practice before and after delivery, method of delivery (cesarean or vaginal delivery, primiparity or multiparity and use of supplements (water or glucose water.Conclusion: This study shows need for special attention and follows up of mothers and neonates at risk for breast feeding jaundice, especially those with inverted nipples or undergraduate for successful breast feeding. On the other hand this study shows encouraging mothers for early lactation especially in the first hour of life decreases the risk for this kind of jaundice.

    The lower incidence of breast cancer in Asian populations where the intake of animal products is lower than that of Western populations has led some to suggest that a vegetarian diet might reduce breast cancer risk. Between 2011 and 2014 we conducted a multicentre hospital based case-control study in eight cancer centres in India. Eligible cases were women aged 30-70 years, with newly diagnosed invasive breast cancer (ICD10 C50). Controls were frequency matched to the cases by age and region of residence and chosen from the accompanying attendants of the patients with cancer or those patients in the general hospital without cancer. Information about dietary, lifestyle, reproductive and socio-demographic factors were collected using an interviewer administered structured questionnaire. Multivariate logistic regression models were used to estimate the odds ratio (OR) and 95% confidence intervals for the risk of breast cancer in relation to lifelong vegetarianism, adjusting for known risk factors for the disease. The study included 2101 cases and 2255 controls. The mean age at recruitment was similar in cases (49.7 years (SE 9.7)) and controls (49.8 years (SE 9.1)). About a quarter of the population were lifelong vegetarians and the rates varied significantly by region. On multivariate analysis, with adjustment for known risk factors for the disease, the risk of breast cancer was not decreased in lifelong vegetarians (OR 1.09 (95% CI 0.93-1.29)). Lifelong exposure to a vegetarian diet appears to have little, if any effect on the risk of breast cancer.

    Due to their lipophilic properties, dioxins (PCDD/PCDFs) and other organohalogen compounds bioaccumulate in the food chain, with diet accounting for over 90% of non-occupational exposures. To date, few epidemiologic studies have examined the relationship between dioxins and breast cancer in human populations. Most have examined risks in occupational cohorts or in populations exposed to dioxins from the Seveso accident6-8. Results from these studies have been conflicting and have largely been limited by a lack of individual-level measures of exposure, small numbers of cases, and inability to account for established breast cancer risk factors. Very little is known about the potential health effects of low-level environmental dioxin contamination. We present data on PCDD/PCDFs, organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) in adipose tissues of women participating in a breast cancer case-control study centered in the San Francisco Bay Area. In addition, we examine distributions of these chemicals in breast and abdominal adipose of women undergoing mastectomies with concurrent breast reconstruction. If concentrations were equivalent, use of abdominal adipose would greatly enhance the pool for controls for future epidemiological studies.

    Full Text Available INTRODUCTION: Chronic diseases and their complications may increase breast cancer risk through known or still unknown mechanisms, or by shared causes. The association between morbidities and breast cancer risk has not been studied in depth. METHODS: Data on all Danish women aged 45 to 85 years, diagnosed with breast cancer between 1994 and 2008 and data on preceding morbidities were retrieved from nationwide medical registries. Odds ratios (OR and 95% confidence intervals (CI were estimated using conditional logistic regression associating the Charlson comorbidity score (measured using both the original and an updated Charlson Comorbidity Index (CCI with incident breast cancer. Furthermore, we estimated associations between 202 morbidity categories and incident breast cancer, adjusting for multiple comparisons using empirical Bayes (EB methods. RESULTS: The study included 46,324 cases and 463,240 population controls. Increasing CCI score, up to a score of six, was associated with slightly increased breast cancer risk. Among the Charlson diseases, preceding moderate to severe renal disease (OR = 1.25, 95% CI: 1.06, 1.48, any tumor (OR = 1.17, 95% CI: 1.10, 1.25, moderate to severe liver disease (OR = 1.86, 95% CI: 1.32, 2.62, and metastatic solid tumors (OR = 1.49, 95% CI: 1.17, 1.89, were most strongly associated with subsequent breast cancer. Preceding myocardial infarction (OR = 0.89, 95% CI: 0.81, 0.99, connective tissue disease (OR = 0.87, 95% CI: 0.80, 0.94, and ulcer disease (OR = 0.91, 95% CI: 0.83, 0.99 were most strongly inversely associated with subsequent breast cancer. A history of breast disorders was associated with breast cancer after EB adjustment. Anemias were inversely associated with breast cancer, but the association was near null after EB adjustment. CONCLUSIONS: There was no substantial association between morbidity measured with the CCI and breast cancer risk.

    In this report, we examined the relationship between mother's breastfeeding history and her risk of breast cancer, in a case-control study in Tunisia between 2006 and 2009. About 400 breast cancer cases and 400 controls were included. Cases and controls were interviewed using a standardized structured questionnaire to obtain information on breastfeeding and other risk factors. Mean duration of breastfeeding per child was significantly associated with a reduced risk of breast cancer for women who breastfed for > 24 months per child. The OR was 0.46 (95% CI, 0.28-0.76) when compared those who breastfed for or = 109 months (OR = 0.42, 95% CI, 0.20-0.84). Stratification by menopausal status showed a reduced risk of breast cancer associated with a longer duration of breastfeeding for both pre- and postmenopausal women. The risk reduction was more consistent for lifetime duration of breastfeeding, the test for trend being significant for both pre- (p = 0.03) and postmenopausal (p = 0.01) women. These results support an inverse association between breastfeeding and breast cancer risk.

    To study the changes in pro-oxidant-antioxidant status in breast, colon and prostate cancer patients as compared to respective controls. Cross-sectional case-control study. The pro-oxidant status was measured by analysing alkanes (ethane and pentane) in exhaled air and lipid peroxidation (as malonaldehyde) in blood samples. The antioxidant capacity was measured by studying blood glutathione concentration, vitamin concentrations and serum antioxidant capacity in liposomes in vitro. Aberdeen hospitals. Breast, prostate and colon cancer cases, and age- and sex-matched control patients (hospitalized for a benign disease). Breast cancer patients were females, prostate cancer patients were males and colon cancer patients were both males and females. Controls were age-matched to within 5 years, sex-matched and matched for smoking habits. The dietary study suggested a higher monoene and polyene fat intake in prostate cancer than in controls while in other cancer patients no significant differences were found. Breast and colon cancer patients tended to have lower vitamin intakes than controls. Pentane concentration in exhaled air increased in breast cancer patients as compared to respective controls. In serum total antioxidant capacity no significant differences were found. Both breast and colon cancer patients showed decreased C18:2 and C20:4 fatty acid concentrations in red blood cells while C22:6 concentration was elevated in breast cancer patients. Oxidative stress may be associated with malignant diseases, suggesting the importance of simultaneous analysis of pro- and antioxidation in the search of mechanistic parameters leading to the tumour formation.

    Patient-reported outcomes and quality of life following mastectomy are not well understood. This study evaluates the quality of life following surgery for breast cancer and compares outcomes following breast-conserving surgery versus total mastectomy with or without reconstruction. A case-controlled cross-sectional study was conducted using the validated BREAST-Q™ questionnaire and a study-specific questionnaire to determine patient's views about surgical outcomes. Questionnaires were completed by patients following breast-conserving surgery and total mastectomy with or without reconstruction and by controls without breast cancer. A one-way ANOVA was used to compare mean BREAST-Q™ scores between groups and post hoc analysis using Tukey's and Kruskal-Wallis tests. BREAST-Q™ questionnaires were completed by 400 women (123 controls, 97 breast conservations, 93 mastectomies without reconstruction, 87 mastectomies with reconstruction). Women who had undergone mastectomy and reconstruction had higher scores in satisfaction with breast and sexual well-being domains compared with women who had breast-conserving surgery, and women who had total mastectomy without reconstruction had the lowest scores in these two domains. There was no difference in psychosocial well-being between the groups. Women who had undergone breast-conserving surgery scored the lowest in the physical well-being chest domain and the majority reported breast asymmetry. Our study suggests that women who undergo total mastectomy and breast reconstruction for cancer achieve a quality-of-life outcome that is at least as good as that following breast-conserving surgery. Furthermore, breast conservation has been found to be associated with lower physical well-being (i.e., more pain and discomfort) in the chest area and poorer sexual well-being outcomes.

  9. Dogma and inquisition in medicine. Breast cancer as a case study.

    1993-04-01

    This case study demonstrates the similarity between the development of dogma and the persecution of deviants during the Spanish Inquisition and that in medicine using breast cancer as an example. Regarding breast cancer, the dogma of therapy became separate from the underlying hypothesis and, like the religious dogma enforced by the Inquisition, it required inflexible adherence. Apostates were publicly chastened. This serves to inhibit debate and the exploration of alternative hypotheses, both of which are essential for the advancement of scientific knowledge. Adherance to dogma is antithetical to the conditional and approximate nature of truth in science.

    Background: The role of vitamin D in breast cancer prevention is equivocal. Saudi Arabian women may be at greater risk of vitamin D deficiency because of a darker skin type and a greater likelihood of reduced ultraviolet B radiation exposure. Data regarding the vitamin D status of Saudi Arabian women and its relation to breast cancer risk are lacking. Objective: The purpose of this research was to evaluate the association between circulating concentrations of 25-hydroxyvitamin D [25(OH)D] and breast cancer risk in Saudi Arabian women. Design: A case-control study was conducted among 120 breast cancer cases and 120 controls. The study population was drawn from patients admitted to King Fahd Hospital in Jeddah, Saudi Arabia, from June to August 2009. Participants completed questionnaires on diet and medical history, and serum samples were collected from all women to measure circulating 25(OH)D concentrations. Results: The participants had a mean age of 47.8 y and a mean body mass index (BMI; in kg/m2) of 30.0. Breast cancer cases had significantly lower (mean ± SD) serum concentrations of 25(OH)D (9.4 ± 6.4 ng/mL) than did controls (15.4 ± 12.3 ng/mL; P = 0.001). In comparison with those in the highest category of vitamin D status for this population (≥20 ng/mL), the adjusted ORs (95% CIs) for invasive breast cancer were 6.1 (2.4, 15.1) for women with a serum 25(OH)D concentration women with a serum concentration of ≥10 to Saudi Arabian women. This trial was registered at clinicaltrials.gov as NCT01817231. PMID:23697705

    The incidence of breast cancer is increasing worldwide, more rapidly in societies that hitherto enjoyed a low incidence of the disease, such as most African countries. Most of the epidemiological data on breast cancer from Africa have been retrospective studies with propensity for bias. This was a case-controlled study of 250 consecutive patients with breast cancer diagnosed between April 1992 and December 1995. An age- and sex-matched control group of patients with non-oncological and non-endocrine diseases was compared. The peak age incidence of breast cancer in the sample studied was 43 years. There was a statistically significant difference in the height and weight of the patients compared with the controls. Patients also tended to be older at first pregnancy and at first lactation, and had a higher mean number of pregnancies. The patients also tended to be of an early birth order, to have lactated less often, to have used contraceptives and to have abused alcohol compared with the controls. The incidence of breast cancer in this environment is increasing. This is partly a result of the changing demographic profile, acquisition of 'western' lifestyle, and the changing socioeconomic profile of the country.

    Young-onset breast cancer (Breast cancer risk factors may contribute to distinct tumor biology and distinct age at onset, but understanding of these relationships has been hampered by limited representation of young women in epidemiologic studies and may be confounded by menopausal status. We examined tumor characteristics and epidemiologic risk factors associated with premenopausal women's and young women's breast cancer in phases I-III of the Carolina Breast Cancer Study (5309 cases, 2022 control subjects). Unconditional logistic regression was used to assess heterogeneity by age (breast cancer risk among young women but with elevated risk among older women. Parity was associated with increased risk among young women and reduced risk among older women, while breastfeeding was more strongly protective for young women. Longer time since last birth was protective for older women but not for young women. In comparison, when we stratified by age, menopausal status was not associated with distinct risk factor or tumor characteristic profiles, except for progesterone receptor status, which was more commonly positive among premenopausal women. Age is a key predictor of breast cancer biologic and etiologic heterogeneity and may be a stronger determinant of heterogeneity than menopausal status. Young women's breast cancer appears to be etiologically and biologically distinct from that among older women.

    Flavonoids have been investigated for possible inverse associations with various chronic degenerative diseases, but there are no epidemiologic data concerning a possible association between several of the main flavonoid categories and breast cancer risk. We have applied recently published data on the flavonoid content of several foods and beverages on dietary information collected in the context of a large case-control study of 820 women with breast cancer and 1548 control women, conducted in Greece. We found a strong, statistically significant inverse association of flavone intake with breast cancer. The odds ratio for an increment equal to one standard deviation of daily flavone intake (i.e. 0.5 mg day(-1)) was 0.87, with 95% confidence interval 0.77-0.97. The association persisted after controlling for fruit and vegetable consumption, or for other flavonoid intake. This inverse association is compatible with and may explain the reported inverse association of breast cancer with consumption of vegetables, particularly leafy vegetables. After controlling for dietary confounding, there was no association of breast cancer risk with flavanones, flavan-3-ols, flavonols, anthocyanidins or isoflavones.

    Breast cancer is the second most common cancer among women in the Kilimanjaro Region of Tanzania. It was tested within a case-control study in this region whether a specific dietary pattern impacts on the breast cancer risk. A validated semi-quantitative Food Frequency Questionnaire was used to assess the dietary intake of 115 female breast cancer patients and 230 healthy age-matched women living in the same districts. A logistic regression was performed to estimate breast cancer risk. Dietary patterns were obtained using principal component analysis with Varimax rotation. The adjusted logistic regression estimated an increased risk for a "Fatty Diet", characterized by a higher consumption of milk, vegetable oils and fats, butter, lard and red meat (OR = 1.42, 95 % CI 1.08-1.87; P = 0.01), and for a "Fruity Diet", characterized by a higher consumption of fish, mango, papaya, avocado and watery fruits (OR = 1.61, 95 % CI 1.14-2.28; P = 0.01). Both diets showed an inverse association with the ratio between polyunsaturated and saturated fatty acids (P/S ratio). A diet characterized by a low P/S ratio seems to be more important for the development of breast cancer than total fat intake.

    Full Text Available Abstract Background Many women in Iran have a relatively high body mass index. To investigate whether the condition contributes to excess breast cancer cases, a case-control study was conducted to assess the relationships between anthropometric variables and breast cancer risk in Tehran, Iran. Methods All incident cases of breast cancer in the Iranian Centre for Breast Cancer (ICBC were identified through the case records. Eligible cases were all postmenopausal women with histological confirmed diagnosis of breast cancer during 1996 to year 2000. Controls were randomly selected postmenopausal women attending the ICBC for clinical breast examination during the same period. The body mass index (BMI was calculated based on weights and heights as measured by the ICBC nursing staff. Both tests for trend and logistic regression analysis were performed to calculate odds ratios and 95% confidence intervals as measures of relative risk. Results In all, 116 breast cancer cases and 116 controls were studied. There were no significant differences between cases and control with regard to most independent variables studied. However, a significant difference was observed between cases and controls indicating that the mean BMI was higher in cases as compared to controls (P = 0.004. Performing logistic regression analysis while controlling for age, age at menopause, family history of breast cancer and parity, the results showed that women with a BMI in the obese range had a three fold increased risk of breast cancer [odds ratio (OR = 3.21, 95% confidence interval (CI: 1.15–8.47]. Conclusion The results suggest that obesity in postmenopausal women could increase risk of breast cancer and it merits further investigation in populations such as Iran where it seems that many women are short in height, and have a relatively high body mass index.

    Full Text Available Abstract Background Household cleaning and pesticide products may contribute to breast cancer because many contain endocrine disrupting chemicals or mammary gland carcinogens. This population-based case-control study investigated whether use of household cleaners and pesticides increases breast cancer risk. Methods Participants were 787 Cape Cod, Massachusetts, women diagnosed with breast cancer between 1988 and 1995 and 721 controls. Telephone interviews asked about product use, beliefs about breast cancer etiology, and established and suspected breast cancer risk factors. To evaluate potential recall bias, we stratified product-use odds ratios by beliefs about whether chemicals and pollutants contribute to breast cancer; we compared these results with odds ratios for family history (which are less subject to recall bias stratified by beliefs about heredity. Results Breast cancer risk increased two-fold in the highest compared with lowest quartile of self-reported combined cleaning product use (Adjusted OR = 2.1, 95% CI: 1.4, 3.3 and combined air freshener use (Adjusted OR = 1.9, 95% CI: 1.2, 3.0. Little association was observed with pesticide use. In stratified analyses, cleaning products odds ratios were more elevated among participants who believed pollutants contribute "a lot" to breast cancer and moved towards the null among the other participants. In comparison, the odds ratio for breast cancer and family history was markedly higher among women who believed that heredity contributes "a lot" (OR = 2.6, 95% CI: 1.9, 3.6 and not elevated among others (OR = 0.7, 95% CI: 0.5, 1.1. Conclusions Results of this study suggest that cleaning product use contributes to increased breast cancer risk. However, results also highlight the difficulty of distinguishing in retrospective self-report studies between valid associations and the influence of recall bias.

    To assess the importance of heredity in the etiology of inflammatory breast cancer (IBC), we compared IBC patients to several carefully chosen comparison groups with respect to the prevalence of first-degree family history of breast cancer. IBC cases (n = 141) were compared to non-inflammatory breast cancer cases (n = 178) ascertained through George Washington University (GWU) with respect to the prevalence of first-degree family history of breast cancer and selected environmental/lifestyle risk factors for breast cancer. Similar comparisons were conducted with subjects from three case-control studies: breast cancer cases (n = 1145) and unaffected controls (n = 1142) from the Cancer Genetic Markers of Susceptibility (CGEMS) study, breast cancer cases (n = 465) and controls (n = 9317) from the Women's Health Initiative (WHI) study, and ovarian cancer cases (n = 260) and controls (n = 331) from a study by University of Toronto (UT). The frequency of first-degree breast cancer family history among IBC cases was 17.0 % compared to 24.4 % for GWU breast cancer cases, 23.9 % and 17.9 % for CGEMS breast cancer cases and controls, respectively, 16.9 % and 12.6 % for WHI breast cancer cases and controls, respectively, and 24.2 % and 11.2 % for UT ovarian cancer cases and controls, respectively. IBC cases had a significantly lower prevalence of parous women than WHI breast cancer cases (OR = 0.46, 95 % CI:0.27-0.81) and controls (OR = 0.31, 95 % CI:0.20-0.49). Oral contraceptive use was significantly higher among IBC cases compared to WHI breast cancer cases (OR = 7.77, 95 % CI:4.82-12.59) and controls (OR = 8.14, 95 % CI:5.28-12.61). IBC cases had a significantly higher frequency of regular alcohol consumption (≥1 drink per day) compared to WHI controls (OR = 1.84, 95 % CI:1.20-2.82) and UT controls (OR = 1.86, 95 % CI:1.07-3.22) and higher (statistically non-significant) prevalence (21.3 %) compared to

    Older adults are underrepresented in medical research for many reasons, including recruitment difficulties. Recruitment of older adults for research studies is often a time-consuming process and can be more challenging when the study involves older adults with unique exposures to traumatic events and from minority groups. The current article provides a brief overview of (a) challenges encountered while recruiting aging women Holocaust survivors for a case control study and (b) strategies used for meeting those challenges. The case group comprised women Holocaust survivors who were recently diagnosed with breast cancer and the control group comprised healthy women from a Holocaust-survivor community in Israel.

    Full Text Available Abstract Background The effect of antioxidants on breast cancer is still controversial. Our objective was to assess the association between antioxidants and breast cancer risk in a large population-based case-control study. Methods The study population included 2,362 cases with pathologically confirmed incident breast cancer (866 premenopausal and 1,496 postmenopausal and 2,462 controls in Canada. Intakes of antioxidants from diet and from supplementation as well as other potential risk factors for breast cancer were collected by a self-reported questionnaire. Results Compared with subjects with no supplementation, 10 years or longer supplementation of zinc had multivariable-adjusted odds ratios (OR and 95% confidence intervals (CI of 0.46 (0.25-0.85 for premenopausal women, while supplementation of 10 years or longer of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc had multivariable-adjusted ORs (95% CIs of 0.74 (0.59, 0.92, 0.58 (0.36, 0.95, 0.79 (0.63-0.99, 0.75 (0.58, 0.97, and 0.47 (0.28-0.78, respectively, for postmenopausal women. No significant effect of antioxidants from dietary sources (including beta-carotene, alpha-carotene, lycopene, lutein and zeaxanthin, vitamin C, vitamin E, selenium and zinc or from supplementation less than 10 years was observed. Conclusions This study suggests that supplementation of zinc in premenopausal women, and supplementation of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc in postmenopausal women for 10 or more years may protect women from developing breast cancer. However, we were unable to determine the overall effect of total dose or intake from both diet and supplement.

    Full Text Available The role of passive smoking on breast cancer risk was unclear. This study aimed to evaluate the association between passive smoking and breast cancer risk among Chinese women.A hospital-based case-control study, including 877 breast cancer cases and 890 controls, frequency-matched by age and residence, was conducted. A structured questionnaire was used to collect information on passive smoking history through face-to-face interview by trained interviewers. Unconditional logistic regression models were used to estimate the association between passive smoking and breast cancer risk. A positive association between any passive smoking exposure and breast cancer risk was observed. Compared with women who were never exposed to passive smoking, women who were ever exposed had a higher breast cancer risk, with the adjusted odds ratio (OR and 95% confidence interval (CI of 1.35 (1.11-1.65. Similar result was found on home passive smoking exposure and breast cancer risk, but not on workplace passive smoking exposure. Women who were ever exposed to tobacco smoke at home had a higher risk of breast cancer compared with never exposed women, with the adjusted OR (95% CI of 1.30 (1.05-1.61. Home passive smoking exposure showed significant dose-response relationships with breast cancer risk in smoker-years, cigarettes/day and total pack-years (Ptrend=0.003, 0.006 and 0.009, respectively. An increased total smoker-years of any passive exposure significantly elevated the risk of breast cancer (Ptrend<0.001. Positive associations and dose-response relationships were found among postmenopausal women and all subtypes of estrogen receptor (ER and progesterone receptor (PR status of breast cancer.Passive smoking was associated with an increased risk of breast cancer among non-smoking Chinese women. A stronger positive association with breast cancer risk was seen mainly among postmenopausal women.

    Low levels of selenium have been associated with a higher risk of cardiovascular diseases and cancer in humans. Since 1984, selenium supplementation through fertilizers has been employed in Finland to increase the very low concentration of selenium in the nation's food supply. As a result, the selenium concentration of Finnish foods became one of the highest in Europe. A decade after selenium supplementation began, the association between toenail selenium and the risk of breast cancer was examined. Case-control study. Eastern Finland. 289 pre- and postmenopausal breast cancer cases and 433 community controls. The diagnosis was unknown at the time the toenail samples were collected. The mean toenail selenium concentration was 0.80 mg/kg in premenopausal cases and 0.84 mg/kg in premenopausal controls: and 0. 77 mg/kg in postmenopausal cases and 0.80 mg/kg in postmenopausal controls. The odds ratio (OR) comparing the highest with the lowest quintiles of toenail selenium concentration was 1.1 (95% CI 0.4-3.2) in premenopausal women and 0.7 (95% CI 0.3-1.5) in postmenopausal women. The intake of retinol, beta-carotene, vitamin E and vitamin C did not change the association between toenail selenium and breast cancer. A decade after selenium supplementation, selenium seems not to be an important factor in the etiology of breast cancer, neither in premenopausal nor postmenopausal women.

    Full Text Available A case – control study of 257 women with breast cancer and 565 control women was conducted to investigate the effect of life-time sport activity on breast cancer risk. Information was collected by questionnaire about sports played, frequency of participation and duration. The activity levels were determined using frequency variable weighted for metabolic equivalents of energy expenditure (MET. Multivariate logistic regression analyses were used to compute odds ratios (ORs and 95% confidence intervals (CIs. A full assessment of confounding and effect modification was undertaken. The odds ratios for increasing tertiles of sport activity were 1.00 (referent, 0.50 (CI: 0.33-0.76 and 0.44 (CI: 0.28-0.64, respectively (P-trend = 0.000. Comparing sport active women to inactive women the OR was 0.49 (CI: 0.35-0.69. Models stratified according to body mass index, age at menarche, age at first full term pregnancy, intake of vegetables and fruits, and experience of stress were examined. In models stratified the risks of breast cancer were also reduced with higher levels of activity in sport. The conclusion is that women who participated in sports have a reduced risk of breast cancer.

    The aim of this study is to identify key characteristics associated with mortality from breast cancer among women with newly diagnosed breast cancer in New Zealand (NZ). Case-control study. All primary breast cancers diagnosed between 01/01/2002 and 31/12/2010 in Waikato, NZ, were identified from the Waikato Breast Cancer Register. A total of 258 breast cancer deaths were identified from 1767 invasive cancers diagnosed over this period. Breast cancer deaths (n = 246) were compared with an age and year of diagnosis matched control group (n = 652) who were alive at the time of the death of the corresponding case and subsequently did not die from breast cancer. Diagnosis through symptomatic presentation, advanced stage, higher grade, absent hormone receptors (i.e. oestrogen and progesterone) and HER-2 amplification were associated with significantly higher risks of breast cancer mortality in bivariate analysis. Tumour stage, grade and hormone receptor status remained significant in the multivariable model, while mode of detection and HER-2 status were non-significant. In the bivariate analysis, Māori women had a higher risk of breast cancer mortality compared to NZ European women (OR 1.34) which was statistically non-significant. However in the adjusted model, risk of mortality was lower for Māori compared to NZ European women, although this was not significant statistically (OR 0.85). Mortality pattern from breast cancer in this study were associated with established risk factors. Ethnic inequity in breast cancer mortality in NZ appears to be largely attributable to delay in diagnosis and tumour related factors. Further research in a larger cohort is needed to identify the full impact of these factors on ethnic inequity in breast cancer mortality. Copyright © 2015 The Royal Society for Public Health.

    The role of passive smoking on breast cancer risk was unclear. This study aimed to evaluate the association between passive smoking and breast cancer risk among Chinese women. A hospital-based case-control study, including 877 breast cancer cases and 890 controls, frequency-matched by age and residence, was conducted. A structured questionnaire was used to collect information on passive smoking history through face-to-face interview by trained interviewers. Unconditional logistic regression models were used to estimate the association between passive smoking and breast cancer risk. A positive association between any passive smoking exposure and breast cancer risk was observed. Compared with women who were never exposed to passive smoking, women who were ever exposed had a higher breast cancer risk, with the adjusted odds ratio (OR) and 95% confidence interval (CI) of 1.35 (1.11-1.65). Similar result was found on home passive smoking exposure and breast cancer risk, but not on workplace passive smoking exposure. Women who were ever exposed to tobacco smoke at home had a higher risk of breast cancer compared with never exposed women, with the adjusted OR (95% CI) of 1.30 (1.05-1.61). Home passive smoking exposure showed significant dose-response relationships with breast cancer risk in smoker-years, cigarettes/day and total pack-years (Ptrend=0.003, 0.006 and 0.009, respectively). An increased total smoker-years of any passive exposure significantly elevated the risk of breast cancer (PtrendPassive smoking was associated with an increased risk of breast cancer among non-smoking Chinese women. A stronger positive association with breast cancer risk was seen mainly among postmenopausal women.

    Full Text Available To investigate the relationship between breastfeeding and breast cancer in Southern Brazil, a case-control design was employed, with two age-matched control groups. A total of 250 cases of breast cancer were identified in women from 20 to 60 years of age, with 1,020 hospital and community controls. The main study variables were occurrence of breastfeeding and duration of breastfeeding. A multivariate conditional logistic regression analysis was employed. According to the results, breastfeeding did not have a protective effect against breast cancer. The odds ratio (OR for women who breastfed was 0.9 (95% CI: 0.8-1.2 compared to women who did not breastfeed. For women who breastfed for six months or less, the OR was 1.0 (95% CI: 0.6-1.8. In pre-menopausal women who breastfed for more than 25 months, the OR was 0.95 (95% CI: 0.5-3.5, and in post-menopausal women OR was 1.27 (95% CI: 0.5-3.1, compared to women who had not breastfeed.

    This study examined the relationship between lifetime history of physical activity and breast cancer risk. The case-control study was conducted on 400 women with histological confirmed breast cancer operated during the 2006-2009 period at Farhat Hached University Hospital, Sousse, Tunisia, and 400 cancer-free controls, aged 25-75 years. The physical activity was assessed using a structured questionnaire on each activity: type, duration, frequency, and intensity. Odds ratios (ORs), 95% confidence intervals (CI) and a full confounding assessment, included in this analysis, were derived using logistic regression. These cases had lower lifetime averages for total physical activity for both forms of activity measurements (hours/week/year and MET-hours/week/year) and (P(trend)<0.001 and P(trend)=0.002, respectively). Significant risk reductions were found in total physical activity for both forms of activity measurements (OR=0.27, 95% CI: 0.18-0.52, OR=0.42, 95% CI: 0.26-0.73, respectively) for the highest versus the lowest level of activity (P(trend)=0.001 and 0.004, respectively). The stratification by menopausal status showed a significant 56% reduction in breast cancer risk for post-menopausal women (P(trend)=0.001, adjusted for age). The risk was further reduced to 68% (P(trend)=0.002, multivariate adjusted). Among pre-menopausal women, the total physical activity was not significantly associated with reduced risk, ORs were 0.88 (95% CI: 0.40-1.99, age adjusted) and 0.43 (95% CI: 0.12-1.38, multivariate adjusted). These data are in concordance with the majority of previous reports which involved physical inactivity as an important risk factor for breast cancer. Copyright © 2011 Elsevier Ltd.

    Pregnancy Associated Breast Cancer (PABC) manifests during pregnancy or within a year following delivery. We sought to investigate differences in management, outcome, clinical, histopathology and immunohistochemistry (IHC) characteristics of PABC and matched controls in a retrospective case control study. PABC and control patients were selected from breast cancer cases of women ≤45 years, diagnosed in the 2nd Department of Pathology, Semmelweis University, Budapest, Hungary between 1998 and 2012. Histopathology information on tumor type, grade, size, T, N, lympho-vascular invasion (LVI), Nottingham Prognostic Index (NPI), associated in situ lesions and IHC charcteristics: ER, PgR, HER2, Ki67, p53 were recorded, IHC-based subtype was assessed, clinical, management and outcome data were analysed. Thirty-one breast cancer cases were pregnancy related. Clinical management data did not differ in cases and controls. Histopathology of disease at presentation was not significantly different, but NPI assessed the PABC group as having poor, whereas controls as having intermediate prognosis. Associated in situ lesion was more often high grade Extensive Intraductal Carcinoma Component (EIC) in PABC. Triple negative and LuminalB prol tumors predominated in PABC. Disease-free and overall survival was inferior compared to controls. PABC patients with LuminalB prol and Triple negative tumors had inferior outcomes. On multivariate analysis inferior prognosis of PABC was associated with pregnancy. Our study has demonstrated inferior outcome of PABC. Difference in tumor biology is reflected by the predominance of triple negative and LuminalB tumors in PABC. The strength of the study is the analysis of complete pathology and IHC data.

    The purpose of this study was to examine factors influencing a woman's decision to participate in a breast cancer prevention clinical trial. Nine healthcare organizations in Massachusetts cooperated in the present project. The authors performed a case-control study to compare responses between the study group (Study of Tamoxifen and Raloxifene [STAR] trial eligible, but not enrolled) and the control group (STAR trial participants) on 12 factors previously identified as barriers to accrual for clinical trials. Eight hypotheses were tested using multiple logistic regression to estimate the strength of the association for each factor on the dependent variable (study participation). The study samples were similar to the general population of eligible breast cancer prevention clinical trial subjects in the counties where the participating organizations were located, the state of Massachusetts, and nationally published STAR trial data. Results of a mailed questionnaire showed that when adjusting for subject demographics, and in the presence of other questions, 4 factors significantly influenced a woman's decision to enroll onto a breast cancer prevention clinical trial more than other eligible subjects: 1) clinician expertise and qualifications (P=.012; odds ratio [OR], 4.903; 95% confidence interval [CI], 1.41-17.04); 2) personal desire to participate (P=.033; OR, 3.16; 95% CI, 1.10-9.06); 3) perceived value of the trial (P=.020; OR, 2.92; 95% CI, 1.18-7.21); and 4) level of trial inconvenience (P=.002; OR, 0.10; 95% CI, 0.02-0.44). Addressing these issues in the relationship between patients and clinicians should improve accrual to breast cancer prevention clinical trials. Copyright (c) 2010 American Cancer Society.

    A case-control study was undertaken to investigate the role of diet in women with breast cancer, and in two groups of women with benign breast disease: epithelial hyperplasia, and fibrocystic disease without hyperplasia. The study provides data which suggest that the consumption of red meat, savoury meals (pizza, pies, stew, etc.) and of starches is disadvantageous, while the consumption of chicken and fish, and of fruit, appears to be beneficial. These patterns were present for both the breast cancer patients and the patients with benign epithelial hyperplasia. One-third of breast cancer patients had changed their diet after their diagnosis, compared to only around 12% in controls and patients with benign breast disease. Overall, the women studied had changed their diet to reduce their intake of sugars, dairy products and meat, and increased their intake of poultry, fish, fruit and vegetables over the past decade; but the breast cancer group was less likely to have made this change.

    Methods: According to the women’s case-control study with simple un-randomized sampling method a total of 245 patients with breast cancer in Ghaem and Emam Reza and Omid hospital from july 2011 to july 2013 entered the study. All patients were on follow-up after therapy, and had a therapy portfolio. In order to achieve better results, questionnaires were distributed among 126 healthy subjects that matched our patient group in terms of age and other factors and were used as the control group. Female sexual function index (FSFI questionnaire was filled out by an independent interviewer and all medical, personal and social ethics were applied. The data was then gathered and the score were analyzed with statistical tests. Results: The study was performed on patients 20 to 50 years, mainly in patients aged 35 to 45 years (51.8%. The average age was 41.44±5.87 years. In our study, the most dysfunction was in sexual desire (57.6%, vaginal moisture (53.1%, sexual excitement (48.2%, orgasm (44.1%, and dyspareunia (52.2% in breast cancer patients. There was significant difference between two group (P<0.001.There is no difference about sexual satisfaction between two groups (P=0.262. Conclusion: Sexual dysfunction is common in breast cancer patients compared to healthy women. Dysfunction in orgasm, dyspareunia, reducing vaginal moisture and sexual desire were common in the breast cancer patient. The results of this study should be used to inform patients and physician about sexual problems.

    Ongoing breast cancer screening programs can only be evaluated using observational study designs. Most studies have observed a reduction in breast cancer mortality, but design differences appear to have resulted in different estimates. Direct comparison of case-control and trial analyses gives more insight into this variation. Here, we performed case-control analyses within the randomized UK Age Trial. The Age Trial assessed the effect of screening on breast cancer mortality in women ages 40-49 years. In our approach, case subjects were defined as breast cancer deaths between trial entry (1991-1997) and 2004. Women were ages 39-41 years at entry. For every case subject, five control subjects were selected. All case subjects were included in analyses of screening invitation (356 case subjects, 1,780 controls), whereas analyses of attendance were restricted to women invited to screening (105 case subjects, 525 age-matched controls). Odds ratios (OR) were estimated with conditional logistic regression. We used and compared two methods to correct for self-selection bias. Screening invitation resulted in a breast cancer mortality reduction of 17% (95% confidence interval [CI]: -36%, +6%), similar to trial results. Different exposure definitions and self-selection adjustments influenced the observed breast cancer mortality reduction. Depending on the method, "ever screened" appeared to be associated with a small reduction (OR: 0.86, 95% CI: 0.40, 1.89) or no reduction (OR: 1.02, 95% CI: 0.48, 2.14) using the two methods of correction. Recent attendance resulted in an adjusted mortality reduction of 36% (95% CI: -69%, +31%) or 45% (95% CI: -71%, +5%). Observational studies, and particularly case-control studies, are an important monitoring tool for breast cancer screening programs. The focus should be on diminishing bias in observational studies and gaining a better understanding of the influence of study design on estimates of mortality reduction.

    Full Text Available Over the last three decades an increase in the incidence of breast cancer has been observed in the previously low-risk Asian countries. This study is designed to determine the risk factors of breast cancer for Pakistani women as little information exists in this regard. A case-control study of 564 female breast cancer cases diagnosed at the two cancer hospitals at Lahore (INMOL and SKMCH during the time period Jan 1, 1998 to Dec 31, 1998 was carried out. Four hundred and forty eight women aged 24-80 years out of 564 cases were complete with respect to defined criteria and were eligible for the study. Population-based controls were selected to match for age of cases in the ratio 1:2. The data were analyzed considering ‘all women’ and then separate analyses were done for ‘premenopausal’ and ‘postmenopausal women’. Women with family history of breast cancer, history of consanguineous marriage, smoking and high BMI (≥28 are at increased risk of breast cancer for all three groups. Early menarche (45 years was a strong determinant of breast cancer. Higher number of full-term pregnancies (>3 was protective for ‘all women’ and ‘premenopausal women’ but in case of ‘postmenopausal women’ the poor with higher number of pregnancies were significantly protected. Late age at first FTP (>25 years is a significant risk factor for postmenopausal women.

    Catechol-O-methyltransferase (COMT) inactivates catechol estrogens by methylation and thus may play a protective role against mutations induced by estrogen metabolites. In this study we investigated the relationship between the Vall58Met polymorphism in the COMT gene and breast cancer risk in a population-based case control study in Syria. We examined 135 breast cancer patients and 107 healthy controls in North Syria to determine the association between the functional genetic Val158Met polymorphism in the COMT gene and female breast cancer risk. There was no significant overall association between the COMT genotype and individual susceptibility to breast cancer. Our data suggest that there may be no overall association between the COMT genotype and breast cancer.

    Epidemiologic characteristics of breast cancer in Iran are significantly different from those in the West and even other regional countries, but little is known about the related factors. A hospital-based case-control study was conducted on 1052 women (526 new cases and 526 controls). Logistic regression was performed to investigate associations of study factors with breast cancer risk. This study introduced occupation (odds ratio [OR]employed/household, 1.77; 95% confidence interval [CI], 1.15-2.69), marital age (OR24-30 y/< 18 y, 2.13; 95% CI, 1.03-4.40), age at first delivery (OR≥ 30 y/< 18 y, 3.53; 95% CI, 1.73-7.18), parity (OR1-2/Nulliparous or never married, 2.61; 95% CI, 1.13-6.02), birth interval (OR30-50 mos/< 18 mos, 2.38; 95% CI, 1.45-3.89), lifetime breastfeeding (OR≥ 42 mos/< 6 mos, 0.37; 95% CI, 0.18-0.77), and menarche age (year) (OR, 0.87; 95% CI, 0.79-0.96) as significant associates of breast cancer. In addition, body mass index (OR, 1.07; 95% CI, 1.02-1.11) and some health-related behaviors including hair coloring on a regular basis (ORyes/no, 1.93; 95% CI, 1.41-2.62), smoking (ORyes/no, 2.02; 95% CI, 1.22-3.34), oral contraceptive usage (ORever/never. 1.46; 95% CI, 1.05-2.04), physical inactivity (ORinactive/regular activity, 1.54; 95% CI, 1.39-1.75), past life stress (ORoften stressful/often calm, 2.40; 95% CI, 1.62-3.56), and regular bedtime (ORoften regular/no, 0.32; 95% CI, 0.19-0.54) were related to a higher risk of breast cancer. This study revealed a significant number of factors that seem to contribute to the risk of breast cancer even more than the other previously introduced factors. Copyright © 2017 Elsevier Inc.

    2010-12-01

    Full Text Available Abstract Introduction Breast cancer is one of the most important health problems in the world and affects a great number of women over the entire globe. This group of tumors rarely presents as bilateral disease and, when it does happen, normally occurs within the same histological type. We report a rare case of concurrent bilateral breast cancer with two different histology types, a breast carcinoma and a breast sarcoma, in a 42-year-old woman referred to our hospital. Case presentation A 42-year-old Caucasian woman admitted to our institute in August 1999, presented with a nodule in the left breast of 3.0 × 2.5 cm, and, in the right breast, one of 1.0 cm, suspected of malignancy and with a clinically negative armpit. Biopsies had revealed invasive mammary carcinoma (right breast and sarcoma (left breast. She was submitted to bilateral modified radical mastectomy. A histological study showed an invasive mammary carcinoma degree II lobular pleomorphic type with invasion of seven of the 19 excised axillary nodes in the right breast and, in the left breast, a sarcoma of the mammary stroma, for which the immunohistochemistry study was negative for epithelial biomarkers and positive for vimentin. Later, she was submitted for chemotherapy (six cycles of 75 mg/m2 5-fluorouracil, epirubicin and cyclophosphamide followed by radiotherapy of the thoracic wall and axillary nodes on the left. Hormone receptors were positive in the tumor of the right breast, and tamoxifen, 20 mg, was prescribed on a daily basis (five years followed by letrozole, 2.5 mg, also daily (five years. She presented no sign of negative evolution in the last consultation. Conclusion The risk of development of bilateral breast cancer is about 1% each year within a similar histological type, but it is higher in tumors with lobular histology. In this case, the patient presented, simultaneously, two histologically distinct tumors, thus evidencing a rare situation.

    Full Text Available Breast cancer is the most common cancer in women worldwide. In the Moroccan context, the role of well-known reproductive factors in breast cancer remains poorly documented. The aim of this study was to explore the relationship between menstrual and reproductive factors and breast cancer risk in Moroccan women in the Fez region.A case-control study was conducted at the Hassan II University Hospital of Fez between January 2014 and April 2015. A total of 237 cases of breast cancer and 237 age-matched controls were included. Information on sociodemographic characteristics, menstrual and reproductive history, family history of breast cancer, and lifestyle factors was obtained through a structured questionnaire. Conditional logistic regression models were used to estimate odds ratios and 95% confidence intervals for breast cancer by menstrual and reproductive factors adjusted for potential confounders.Early menarche (OR = 1.60, 95% CI: 1.08-2.38 and nulliparity (OR = 3.77, 95% CI: 1.98-7.30 were significantly related to an increased risk of breast cancer, whereas an early age at first full-term pregnancy was associated with a decreased risk of breast cancer (OR = 0.41, 95% CI: 0.25-0.65.The results of this study confirm the role of established reproductive factors for breast cancer in Moroccan women. It identified some susceptible groups at high risk of breast cancer. Preventive interventions and screening should focus on these groups as a priority. These results should be confirmed in a larger, multicenter study.

    The purpose of the study was the identification of risk factors for benign breast diseases (BBD); 257 women with BBD diagnosed through pathological anatomy or cytology and a matched control for each were studied. Subjects were selected at The State University of Campinas Hospital and at a private clinic. To enter the study cases had to have a first diagnosis of BBD between October 1979 and August 1984. The following BBD were considered: dysplasia, fibroadenoma, cystic disease, papilloma and ductal ectasia. Reproductive variables were studied as risk factors, including menstrual ovulatory cycles. The date on which the BBD was diagnosed was defined as the index date. For controls, data were considered up to when they had reached the same age as the matched case on the occasion of her diagnosis. Nulliparity was a risk factor for BBD. First birth at or above age 30 was a protective factor. Women who had used contraceptive pills for two or more years had a significantly lower risk than those who had never used them. The number of menstrual ovulatory cycles was not found to be associated with the risk of BBD. The results obtained from the study of Brazilian women confirm some of the conclusions found in the literature, mainly those that associate some reproductive variables with the risk of BBD. A few of these variables are also confirmed as risk factors for breast cancer.

    Deleted in colorectal carcinoma (DCC), a netrin-1 dependence receptor, is correlated with cell progression, migration, and adhesion. Evidence indicated that DCC was frequently down-regulated in many cancers. However, the association of DCC with breast cancer remains uncertain. We conducted a case-control study to investigate the impact of three DCC gene variants (rs2229080, rs7504990, and rs4078288) on breast cancer susceptibility in Chinese women. This study included 560 breast cancer patients and 583 age-matched healthy controls from Northwest China. The three gene variants were genotyped via Sequenom MassARRAY. Odds ratios (ORs) and 95% confidence intervals (CIs) were utilized to evaluate the associations. We found that individuals with the rs2229080 C/G, C/C, and C/G-CC genotypes had a higher breast cancer risk, and the minor allele C was associated with increased breast cancer risk in an allele model. We observed a significantly decreased breast cancer risk with the rs7504990 C/T, T/T, and C/T-T/T genotypes, and the minor allele T was protective against breast cancer in an allele model. In addition, rs2229080 was associated with the axillary lymph node (LN) metastasis status. An age-stratified analysis revealed an association between rs2229080 and reduced breast cancer risk among older patients (≥ 49 years). Furthermore, the haplotype analysis showed that the Crs2229080Crs7504990Ars4078288 haplotype was associated with a decreased breast cancer risk. However, the results indicated a lack of association between rs4078288 and breast cancer risk. These findings affirmed that rs2229080 and rs7504990 polymorphisms in DCC might be related with breast cancer susceptibility in Chinese women.

    A number of studies have evidenced the effect of modifiable lifestyle factors such as diet, breastfeeding and nutritional status on breast cancer risk. However, none have addressed the missing data problem in nutritional epidemiologic research in South America. Missing data is a frequent problem in breast cancer studies and epidemiological settings in general. Estimates of effect obtained from these studies may be biased, if no appropriate method for handling missing data is applied. We performed Multiple Imputation for missing values on covariates in a breast cancer case-control study of Córdoba (Argentina) to optimize risk estimates. Data was obtained from a breast cancer case control study from 2008 to 2015 (318 cases, 526 controls). Complete case analysis and multiple imputation using chained equations were the methods applied to estimate the effects of a Traditional dietary pattern and other recognized factors associated with breast cancer. Physical activity and socioeconomic status were imputed. Logistic regression models were performed. When complete case analysis was performed only 31% of women were considered. Although a positive association of Traditional dietary pattern and breast cancer was observed from both approaches (complete case analysis OR=1.3, 95%CI=1.0-1.7; multiple imputation OR=1.4, 95%CI=1.2-1.7), effects of other covariates, like BMI and breastfeeding, were only identified when multiple imputation was considered. A Traditional dietary pattern, BMI and breastfeeding are associated with the occurrence of breast cancer in this Argentinean population when multiple imputation is appropriately performed. Multiple Imputation is suggested in Latin America’s epidemiologic studies to optimize effect estimates in the future. PMID:27892664

    There is strong evidence that breast cancer risk is influenced by environmental factors. Blood lipid and lipoprotein levels are also influenced by environmental factors and are associated with some breast cancer risk factors. We examined whether serial measures of serum lipids and lipoproteins were associated with breast cancer risk. We carried out a nested case-control study within a randomized long-term dietary intervention trial with 4690 women with extensive mammographic density followed for an average of 10 years for breast cancer incidence. We measured lipids in an average of 4.2 blood samples for 279 invasive breast cancer case subjects and 558 matched control subjects. We calculated subaverages of lipids for each subject based on menopausal status and use of hormone replacement therapy (HRT) at blood collection and analyzed their association with breast cancer using generalized estimating equations. All statistical tests were two-sided. High-density lipoprotein-cholesterol (HDL-C) (P = .05) and apoA1 (P = .02) levels were positively associated with breast cancer risk (75(th) vs 25(th) percentile: HDL-C, 23% higher; apoA1, 28% higher) and non-HDL-C (P = .03) and apoB (P = .01) levels were negatively associated (75(th) vs 25(th) percentile: non-HDL-C, 19% lower; apoB, 22% lower). These associations were observed only when lipids were measured when HRT was not used. Total cholesterol and triglyceride levels were not statistically significantly associated with breast cancer risk. These results demonstrate that serum lipids are associated with breast cancer risk in women with extensive mammographic density. The possibility that interventions for heart disease prevention, which aim to reduce non-HDL-C or raise HDL-C, may have effects on breast cancer risk merits examination. © The Author 2015.

    Breast cancer (BC) is the main common cause of cancer mortality among women in the world. This study aims at investigating BC epidemiology and identifying the different risk factors associated and the most affecting ones among women in the Gaza Strip, Palestine. This study was a hospital-based case-control (1:2), as the study was carried out over the period of October 2014 to February 2015. A total of 105 BC patients, chosen from Al-Shifa Hospital in Gaza City and European hospital for the south governorate, were the case and compared to 209 women as a control group who matched the cases in age, residence, and with no history of breast problems. The age of the enrolled cases and controlled ranged between 18 to 60 years. The face-to-face interview was conducted during the patient visit to the oncology department and the control visit in their home. The result illustrated that women who had late pregnancy (> 35 years) (odds ratio [OR], 11.56; 95% confidence interval [CI], 1.64-81.35), or high body mass index (BMI; ≥ 30 kg/m2) (OR, 4.70; 95% CI, 1.62-13.69), or first-degree family history of BC (OR, 2.7; 95% CI, 1.04-7.20), or hypertensive patients (OR, 12.13; 95% CI, 1.93-76.10), or diabetic (OR, 6.84; 95% CI, 1.77-26.36) were more likely to have increased BC risk. The findings of the present study suggest that positive family history of BC, high BMI, and some common diseases (hypertension, diabetes mellitus) may be the epigenetic factors promoting the occurrence of BC.

    Full Text Available Abstract Background Pesticides are widely used in households to control insects and weeds. Several studies, over the past decades, have examined the possible relationship of serum concentration of organochlorine pesticides and the development of breast cancer. However, little data exists regarding an association between self-reported, residential exposure to pesticides and breast cancer risk. We, therefore, present a case-control study examining self-reported exposure to household pesticides with regard to associated risk of breast cancer. Methods This study was conducted in the area in and around New York City, NY and included 1205 patients (447 cases and 758 controls. Cases were defined as women with newly diagnosed breast cancer or carcinoma in-situ, while controls included women with benign breast diseases or those undergoing non-breast related surgery. All patients were asked a series of questions to determine their pesticide exposure, including the type of pesticide, location of exposure (inside vs. outside the home, who applied the pesticide (self vs. a professional and duration of pesticide use. Logistic regression models were used to estimate unadjusted and adjusted odds ratios (OR and corresponding 95% confidence intervals (CI. Results The most common pests encountered in participants' homes were ants, carpenter ants, and cockroaches. The calculated adjusted odds ratios for both self and professionally applied pesticides, specifically against the above mentioned insects, with regard to breast cancer risk were 1.25 (95% CI: 0.79-1.98 and 1.06 (95% CI: 0.65-1.73, respectively. Similarly, odds ratios and confidence intervals were calculated for other types of pesticides. Conclusions Overall, the results of our study did not show an association between self-reported exposure to pesticides and breast cancer risk. Future studies, utilizing a larger sample size and more specific detail on time frame of pesticide exposure, are needed to

    Full Text Available This study aims to examine the association of breast cancer with dietary patterns among Chinese women. A population-based case-control study was conducted in Jiangsu, China. Newly diagnosed primary breast cancer patients were recruited as cases (n = 818. Controls (n = 935, selected from the general population, were frequency matched to cases. A validated food frequency questionnaire was used to assess dietary intake. Dietary patterns were identified by factor analysis and multivariable odds ratios (OR and 95% confidence intervals (CI were estimated. Four dietary patterns were identified: salty, vegetarian, sweet and traditional Chinese. The traditional Chinese pattern was found to be robustly associated with a lower risk of breast cancer among both pre- and post-menopausal women (4th vs. 1st quartile: OR for pre- and post-menopausal women was 0.47 and 0.68, respectively. Women with high factor scores of the sweet pattern also showed a decreased risk of breast cancer (4th vs. 1st quartile: OR for pre- and post-menopausal women was 0.47 and 0.68, respectively. No marked association was observed between a vegetarian pattern or a salty pattern and breast cancer. These findings indicate that dietary patterns of the traditional Chinese and the sweet may favorably associate with the risk of breast cancer among Chinese women.

    Several studies have investigated the relation between benign breast diseases (BBD) and food intake. However, dietary patterns of these patients have not been taken into consideration up to now. The aim of this study is to determine the association between dietary patterns and BBD. In this case-control study, ninety-six patients with BBD and seventy controls were selected from women attending the Iranian Center for Breast Cancer affiliated with Academic Center for Education, Culture and Research. Demographic, physical activity and semi-quantitative FFQ were completed. The main dietary patterns were extracted by factor analysis. Two major dietary patterns emerged: Healthy dietary pattern including fish, poultry, eggs, low-fat dairy products, vegetables, legumes, nuts and seeds, whole grains, oil and mayonnaise, olives, fruits; and Unhealthy dietary pattern including red meats, organ and processed meats, high-fat dairy products, refined grains, sweets and desserts, animal and solid fats. After adjustment for age, BMI and energy intake, the participants in the highest tertile of Healthy dietary pattern (OR 0·44; 95 % CI 0·20, 0·99) were less likely to have BBD compared with those in the first tertile. After adjustment for other confounding variables, this relationship still remained close to significant level. However, higher consumption of Unhealthy dietary pattern was not associated with the risk of BBD. In conclusion, Healthy dietary pattern might be inversely associated with the risk of BBD; however, this result should be interpreted with caution. Future studies are needed to confirm our findings.

    Some previous studies have suggested that exposure to engine exhausts may increase risk of breast cancer. In a population-based case-control study of breast cancer in Western Australia we assessed occupational exposure to engine exhausts using questionnaires and telephone interviews. Odds Ratios (OR) and 95% Confidence Intervals (CI) were calculated using logistic regression. We found no association between risk of breast cancer and occupational exposure to diesel exhaust (OR 1.07, 95%CI: 0.81-1.41), gasoline exhaust (OR 0.98, 95%CI: 0.74-1.28), or other exhausts (OR 1.08, 95%CI: 0.29-4.08). There were also no significant dose- or duration-response relationships. This study did not find evidence supporting the association between occupational exposures to engine exhausts and breast cancer risk. Am. J. Ind.

    Previous research has not been conclusive regarding the association between selenium (Se) and breast cancer. This study was conducted to clarify if there is an association between prediagnostic serum Se levels and breast cancer risk. A population based cohort, the Malmö Diet and Cancer Study, was used and linked with the Swedish cancer registry up to 31 December 2013. Our study included 1,186 women with breast cancer and an equal number of controls. Selenium levels were analysed from stored serum samples. The included individuals were divided into quartiles based on Se value and we compared breast cancer cases with controls using logistic regression yielding odds ratios (OR) with 95% confidence intervals. Serum Se was also analysed as a continuous variable regarding breast cancer risk. The analyses were adjusted for established risk factors and stratified on smoking status and body mass index (BMI). When comparing the highest Se quartile with the lowest, the adjusted OR for breast cancer was 0.98 (0.75-1.26). With selenium as a continuous variable the adjusted OR was 1.00 (1.00-1.01) per 10 ng/ml. When comparing the highest with the lowest Se quartile in women with BMI > 25 kg/m(2) the adjusted OR was 0.77 (0.53-1.14). We conclude that it is unlikely that prediagnostic serum selenium is overall associated with breast cancer risk and no modifying effect from BMI or smoking was seen. © 2017 UICC.

    It has been suggested that long-term activation of the body's stress-response system and subsequent overexposure to stress hormones may be associated with increased morbidity. However, evidence on the impact of major life events on mortality from breast cancer (BC) remains inconclusive. The main aim of this study is to investigate whether major negatively or positively experienced life events before or after diagnosis have an effect on BC-specific mortality in women who have survived with BC for at least 2 years. We conducted a case fatality study with data on life events from a self-administered survey and data on BC from the Finnish Cancer Registry. Cox models were fitted to estimate BC mortality hazard ratios (MRs) between those who have undergone major life events and those who haven't. None of the pre-diagnostic negative life events had any effect on BC-specific mortality. Regarding post-diagnostic events, the effect was greatest in women with moderate scores of events. As for event-specific scores, increased BC mortality was observed with spouse unemployment, relationship problems, and death of a close friend. By contrast, falling in love and positive developments in hobbies were shown to be associated with lower BC mortality (MRs 0.67, 95%CI: 0.49-0.92 and 0.74, 95%CI: 0.57-0.96, respectively). In an analysis restricted to recently diagnosed cases (2007), also death of a child and of a mother was associated with increased BC mortality. Some major life events regarding close personal relationships may play a role in BC-specific mortality, with certain negative life events increasing BC mortality and positive events decreasing it. The observed favorable associations between positive developments in romantic relationships and hobbies and BC mortality are likely to reflect the importance of social interaction and support.

    In 1972, Beck introduced an inventory (BDI) for rapid screening of depression. The associations between the BDI and the risk of breast cancer (BC) are rarely considered together in prospective studies. In an extension of the Kuopio Breast Cancer Study, 115 women with breast cancer symptoms were semi-structurally interviewed in-depth as well as asked to complete standardised questionnaires (Forsen, Spielberger, MADRS), and all study variables were obtained before any diagnostic procedures were carried out. BDI was used to evaluate the depression of the study participants. The clinical examinations and biopsies showed BC in 34 patients, benign breast disease (BBD) in 53 patients, and 28 individuals were shown to be healthy (HSS). There was a trend for the women with HSS to have less sadness (BDI mean score, 0.27) than those of the BC (BDI mean score, 0.56) and BBD groups (BDI mean score, 0.49). The HSS group tended to be less pessimistic (BDI mean score, 0.15) than the patients in the BC group (BDI mean score, 0.44) and in the BBD group (BDI mean score, 0.42). The HSS group also had less self-accusation (BDI mean score, 0.19) than the patients in the BC group (BDI mean score, 0.50) and the patients in the BBD group (BDI mean score, 0.62). The HSS group also reported less work inhibition and weight loss than the patients in the BC group and in the BBD group. The mean sum of the scores of BDI variables was significantly lower in the HSS group (BDI mean score, 7.1) than in the BC (BDI mean score, 8.4) or BBD groups (BDI mean score, 8.8). The results of this study do not support a specific link between BDI and breast cancer risk. However, the patients with BC and BBD tended to have an increased risk for depressive symptoms.

    The usefulness of case-control studies has been questioned. Our aim was to evaluate the long-term effect of screening on breast cancer mortality within the population-based mammography programme in Finland using a case-control design, and to compare the analyses with the earlier cohort study. The cases were women invited to screening, diagnosed and died from breast cancer in 1992-2011 while being 50-84 years at death. We chose 10 controls for each case with non-restrictive eligibility criteria. Our data included 1907 cases and 18 978 matched controls. We analysed associations between the screening participation and the risk of breast cancer death using the conditional Cox proportional hazards model. The effect estimates were corrected for self-selection bias. An overall effect of screening was 0.67 (95% confidence interval (CI): 0.49-0.90), and that remained unchanged over time. Analyses with matching criteria comparable to the cohort study yielded an effect (0.70, 95% CI: 0.49-1.00) in 1992-2003 similar to that of the previous cohort analysis (0.72, 95% CI: 0.56-0.88). Organised mammography screening decreases mortality from breast cancer by 33% among the participants. If made comparable, a case-cohort study can yield effect estimates similar to a cohort study.

    Night work involving disruption of circadian rhythm was suggested as a possible cause of breast cancer. We examined the role of night work in a large population-based case-control study carried out in France between 2005 and 2008. Lifetime occupational history including work schedules of each night work period was elicited in 1,232 cases of breast cancer and 1,317 population controls. Thirteen percent of the cases and 11% of the controls had ever worked on night shifts (OR = 1.27 [95% confidence interval = 0.99-1.64]). Odds ratios were 1.35 [1.01-1.80] in women who worked on overnight shifts, 1.40 [1.01-1.92] in women who had worked at night for 4.5 or more years, and 1.43 [1.01-2.03] in those who worked less than three nights per week on average. The odds ratio was 1.95 [1.13-3.35] in women employed in night work for >4 years before their first full-term pregnancy, a period where mammary gland cells are incompletely differentiated and possibly more susceptible to circadian disruption effects. Our results support the hypothesis that night work plays a role in breast cancer, particularly in women who started working at night before first full-term pregnancy. Copyright © 2012 UICC.

    Epidemiologic and animal data indicate that night shift work might increase the risk for breast cancer. We evaluated the association of night work with different clinical types of breast cancer in a population based case-control study (MCC-Spain study) taking into account chronotype, an individual characteristic that may relate to night shift work adaptation. Lifetime occupational history was assessed by face-to-face interviews and shift work information was available for 1708 breast cancer cases and 1778 population controls from 10 Spanish regions, enrolled from 2008 to 2013. We evaluated three shift work domains, including shift work type (permanent vs rotating), lifetime cumulative duration and frequency. We estimated odds ratios (OR) for night work compared to day work using unconditional logistic regression models adjusting for confounders. Having ever worked permanent or rotating night shift was associated with an increased risk for breast cancer compared to day workers [odds ratio (OR) 1.18; 95 % CI 0.97, 1.43]. Chronotype was differentially associated with breast cancer depending on the duration of night shift work. Risk was higher in women with invasive tumors (OR 1.23; 95 % CI 1.00, 1.51) and for estrogen and progestagen positive tumors among premenopausal women (OR 1.44; 95 % CI 1.05, 1.99). Having ever performed night shift was associated with a small increased risk for breast cancer and especially in subgroups of women with particular hormone related characteristics.

    Circulating osteoprotegerin (OPG), a member of the receptor activator of nuclear factor kappa-B (RANK) axis, may influence breast cancer risk via its role as the decoy receptor for both the RANK ligand (RANKL) and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). Circulating OPG and breast cancer risk has been examined in only one prior study. A case-control study was nested in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. A total of 2008 incident invasive breast cancer cases (estrogen receptor (ER)+, n = 1622; ER-, n = 386), matched 1:1 to controls, were included in the analysis. Women were predominantly postmenopausal at blood collection (77%); postmenopausal women included users and non-users of postmenopausal hormone therapy (HT). Serum OPG was quantified with an electrochemiluminescence assay. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated using conditional logistic regression. The associations between OPG and ER+ and ER- breast cancer differed significantly. Higher concentrations of OPG were associated with increased risk of ER- breast cancer (top vs. bottom tertile RR = 1.93 [95% CI 1.24-3.02]; p trend  = 0.03). We observed a suggestive inverse association for ER+ disease overall and among women premenopausal at blood collection. Results for ER- disease did not differ by menopausal status at blood collection (p het  = 0.97), and we observed no heterogeneity by HT use at blood collection (p het  ≥ 0.43) or age at breast cancer diagnosis (p het  ≥ 0.30). This study provides the first prospective data on OPG and breast cancer risk by hormone receptor subtype. High circulating OPG may represent a novel risk factor for ER- breast cancer.

    Full Text Available Abstract Background Older paternal age may increase the germ cell mutation rate in the offspring. Maternal age may also mediate in utero exposure to pregnancy hormones in the offspring. To evaluate the association between paternal and maternal age at birth with the risk of breast cancer in female offspring, a case-control study was conducted in Korea. Methods Histologically confirmed breast cancer cases (n = 1,011 and controls (n = 1,011 with no present or previous history of cancer, matched on year of birth and menopausal status, were selected from several teaching hospitals and community in Seoul during 1995–2003. Information on paternal and maternal ages and other factors was collected by interviewed questionnaire. Odds ratio (OR and 95% confidence interval (95% CI were estimated by unconditional logistic regression model adjusting for family history of breast cancer in 1st or 2nd degree relatives, and lifetime estrogen exposure duration. Results The risk of breast cancer significantly increased as the paternal age increased (p for trend = 0.025. The association was stronger after controlling for maternal age; women whose fathers were aged ≥40 years at their birth had 1.6-fold increased risk of breast cancer compared with fathers aged Conclusion These findings suggest that older paternal age increases the risk of breast cancer in their female offspring.

    In this study we assessed the dietary phytochemical index in relation to the risk of breast cancer in women. This case-control study was conducted on 100 incident breast cancer cases and 175 healthy controls. Data regarding socio-demographic factors, medical history, medications, and anthropometric measurements were collected. Dietary data were obtained using a validated food frequency questionnaire and a energy-adjusted dietary phytochemical index (PI) was calculated. The odds ratios of breast cancer were assessed across energy- adjusted PI quartile categories. The mean age of participants was 46.2±8.9 and 45.9±9.4 years in cases and controls, respectively. The mean PI across quartile categories was 13.9±2.6, 21.1±1.8, 26.7±2.1, 41.6±10.2 in the first, second, third and fourth quartiles, respectively. After adjustment for all potential confounders, the risk of breast cancer in the forth quartile of dietary PI was significantly decreased (OR=0.08, 95%CI=0.01-0.84). Higher intake of phytochemical-rich foods is associated with lower risk of breast cancer.

    Fine needle aspiration cytology (FNAC) is a simple, rapid, inexpensive, and reliable method of diagnosis of breast mass. Cytoprognostic grading in breast cancers is important to identify high-grade tumors. Computer-assisted image morphometric analysis has been developed to quantitate as well as standardize various grading systems. To apply nuclear morphometry on cytological aspirates of breast cancer and evaluate its correlation with cytomorphological grading with derivation of suitable cutoff values between various grades. Descriptive cross-sectional hospital-based study. This study included 64 breast cancer cases (29 of grade 1, 22 of grade 2, and 13 of grade 3). Image analysis was performed on Papanicolaou stained FNAC slides by NIS -Elements Advanced Research software (Ver 4.00). Nuclear morphometric parameters analyzed included 5 nuclear size, 2 shape, 4 texture, and 2 density parameters. Nuclear size parameters showed an increase in values with increasing cytological grades of carcinoma. Nuclear shape parameters were not found to be significantly different between the three grades. Among nuclear texture parameters, sum intensity, and sum brightness were found to be different between the three grades. Nuclear morphometry can be applied to augment the cytology grading of breast cancer and thus help in classifying patients into low and high-risk groups.

    The putative relationship between diet, including its inflammatory potential, and breast cancer has been studied extensively, but results remain inconsistent. Using data from a large Italian case-control study conducted between 1991 and 1994, we examined the association between the dietary inflammatory index (DII) and odds of breast cancer. DII scores were computed using a validated 78-item food frequency questionnaire. Subjects were 2569 women with incident, histologically confirmed breast cancer and 2588 controls admitted to hospital for acute, non-hormone-related diseases. Odds ratios (ORs) and 95% confidence intervals (CIs) based on continuous and quintiles of DII were estimated by multiple logistic regression adjusting for age, study center, education, BMI, parity, menopausal status, family history of hormone-related cancers, and total energy intake. Women in quintiles 2, 3, 4 and 5 had ORs of breast cancer of 1.33 (95% CI: 1.11, 1.59), 1.37 (95% CI: 1.13, 1.66), 1.41 (95% CI: 1.15, 1.73), and 1.75 (95% CI: 1.39, 2.21), respectively, compared to women in quintile 1. One-unit increase in DII increased the odds of having breast cancer by 9% (95% CI: 1.05, 1.14).

    Lifestyle factors, including food and nutrition, physical activity, body composition and reproductive factors, and single nucleotide polymorphisms (SNPs) are associated with breast cancer risk, but few studies of these factors have been performed in the Japanese population. Thus, the goals of this study were to validate the association between reported SNPs and breast cancer risk in the Japanese population and to evaluate the effects of SNP genotypes and lifestyle factors on breast cancer risk. A case-control study in 472 patients and 464 controls was conducted from December 2010 to November 2011. Lifestyle was examined using a self-administered questionnaire. We analyzed 16 breast cancer-associated SNPs based on previous GWAS or candidate-gene association studies. Age or multivariate-adjusted odds ratios (OR) and 95% confidence intervals (95% CI) were estimated from logistic regression analyses. High BMI and current or former smoking were significantly associated with an increased breast cancer risk, while intake of meat, mushrooms, yellow and green vegetables, coffee, and green tea, current leisure-time exercise, and education were significantly associated with a decreased risk. Three SNPs were significantly associated with a breast cancer risk in multivariate analysis: rs2046210 (per allele OR=1.37 [95% CI: 1.11-1.70]), rs3757318 (OR=1.33[1.05-1.69]), and rs3803662 (OR=1.28 [1.07-1.55]). In 2046210 risk allele carriers, leisure-time exercise was associated with a significantly decreased risk for breast cancer, whereas current smoking and high BMI were associated with a significantly decreased risk in non-risk allele carriers. In Japanese women, rs2046210 and 3757318 located near the ESR1 gene are associated with a risk of breast cancer, as in other Asian women. However, our findings suggest that exercise can decrease this risk in allele carriers.

    Full Text Available BACKGROUND: The association between breast cancer and tobacco smoke is currently unclear. The aim of this study was to assess the effect of smoking behaviours on the risk of breast cancer among three ethnic groups of New Zealand women. METHODS: A population-based case-control study was conducted including breast cancer cases registered on the New Zealand Cancer Registry between 2005 and 2007. Controls were matched by ethnicity and 5-year age-group. Logistic regression was used to estimate the association between breast cancer and smoking at different time points across the lifecourse, for each ethnic group. Estimated odds ratios (OR were adjusted for established risk factors. RESULTS: The study comprised 1,799 cases (302 Māori, 70 Pacific, 1,427 non-Māori/non-Pacific and 2,540 controls (746 Māori, 191 Pacific, 1,603 non-Māori/non-Pacific. There was no clear association between smoking and breast cancer for non-Māori/non-Pacific women, although non-Māori/non-Pacific ex-smokers had statistically significant increased risk of breast cancer when smoking duration was 20 years or more, and this remained significant in the fully adjusted model (OR 1.31, 95% CI 1.03 to 1.66. Māori showed more consistent increased risk of breast cancer with increasing duration among current smokers (<20 years OR 1.61, 95% CI 0.55 to 4.74; 20+ years OR 2.03, 95% CI 1.29 to 3.22. There was a clear pattern of shorter duration since smoking cessation being associated with increased likelihood of breast cancer, and this was apparent for all ethnic groups. CONCLUSION: There was no clear pattern for cigarette smoking and breast cancer incidence in non-Māori/non-Pacific women, but increased risks were observed for Māori and Pacific women. These findings suggest that lowering the prevalence of smoking, especially among Māori and Pacific women, could be important for reducing breast cancer incidence.

    Previous studies have suggested that the occurrence of pregnancy concomitantly with a diagnosis of breast cancer may affect the evolution of the neoplasia. The present study aimed to compare pregnancy-associated breast cancer (PABC) patients with non-pregnant cancer patients (controls) in relation to the time taken to diagnose the disease, tumor characteristics and mortality. A retrospective, paired case-control study was conducted at the Hospital da Santa Casa de Misericórdia and Centro de Quimioterapia Antiblástica e Imunoterapia in Belo Horizonte, Brazil. The study involved 87 PABC and 252 control patients. The influence of covariables (interval between first symptoms and diagnosis, tumor histology, size of primary tumor, distant metastasis, grade of malignancy, hormone receptor status and axillary lymph node involvement) and the pregnancy variable on overall survival was investigated using univariate and multivariate analyses. The median overall survival for PABC patients of 30.1 months (95% confidence interval, CI: 19.4-40.9 months) was significantly different (P = 0.005) from that of the control group (53.1 months; 95% CI: 35.1-71.0 months). The cumulative overall survivals after five and ten years were, respectively, 29.7 and 19.2% for PABC patients, and 47.3 and 34.8% for control patients (P = 0.005). Tumor size, grade of malignancy, distant metastasis and pregnancy were independent factors that significantly modified disease prognosis. Pregnancy was an independent prognostic factor. The overall survival of PABC patients was shorter than that of non-pregnant patients.

    We are investigating the feasibility of improving breast cancer risk prediction by computerized mammographic parenchymal pattern (MPP) analysis. A case-control study was conducted to investigate the association of the MPP measures with breast cancer risk. The case group included 168 contralateral CC-view mammograms of breast cancer patients dated at least one year prior to cancer diagnosis, and the control group included 522 CC-view mammograms from one breast of normal subjects. We extracted and compared four types of statistical texture feature spaces that included run length statistics and region size statistics (RLS/RSS) features, spatial gray level dependence (SGLD) features, gray level difference statistics (GLDS) features, and the feature space combining these three types of texture features. A linear discriminant analysis (LDA) classifier with stepwise feature selection was trained and tested with leave-one-case-out resampling to evaluate whether the breast parenchyma of future cancer patients could be distinguished from those of normal subjects in each feature space. The areas under ROC curves (Az) were 0.71, 0.72, 0.71 and 0.76 for the four feature spaces, respectively. The Az obtained from the combined feature space was significantly (pbreast cancer risk and four categories of MPP measures: 0.2 (C4) while patient age was treated as a confounding factor. The adjusted ORs of breast cancer for C2, C3 and C4 were 3.23, 7.77 and 25.43, respectively. The preliminary result indicated that our proposed computerized MPP measures were strongly associated with breast cancer risk.

    We report a case-control, breast cancer epidemiological study through mining people stories from the Internet. The aim of the study is to test whether mining openly available, personal stories from the Internet can be a cost-effective way for reliable epidemiological discoveries. As a case study, we focus on the association between breast cancer risk and pregnancy, which is clearly established through controlled clinical survey studies. Specifically, we mined 30,000 online obituary articles. Replicating a case-control study design, our web mining based approach confirmed the general trends reported by traditional epidemiological studies. Our web mining study demonstrates promising preliminary evidence that online content mining can be a cost-effective way for epidemiological knowledge discovery.

    Choline and betaine are important for DNA methylation and synthesis, and may affect tumor carcinogenesis. To our knowledge, no previous study has examined the association between serum choline and betaine and breast cancer risk. This study aimed to examine whether serum choline and betaine were inversely associated with breast cancer risk among Chinese women. This hospital-based case-control study consecutively recruited 510 breast cancer cases and 518 frequency-matched (age and residence) controls, and blood samples were available for 500 cases and 500 controls. Serum choline and betaine were assayed by high-performance liquid chromatography-tandem mass spectrometry. Multiple unconditional logistic regression was used to estimate odds ratios (ORs) and 95 % confidence intervals (CIs). An inverse association with breast cancer risk was observed for serum betaine (fourth vs first quartile adjusted OR 0.68, 95 % CI 0.47-0.97) and for the ratio of serum betaine to choline (fourth vs first quartile adjusted OR 0.70, 95 % CI 0.48-1.00), but not for serum choline (fourth vs first quartile adjusted OR 0.80, 95 % CI 0.56-1.15). Serum betaine was inversely associated with breast cancer risk in subjects with below-median dietary folate intake (fourth vs first quartile adjusted OR 0.48, 95 % CI 0.30-0.77). This study suggested that serum betaine but not choline was inversely associated with breast cancer risk. This result needed to be further confirmed by the prospective studies.

    To explore possible relationships among blood factors, family history of breast cancer (BC) and the risk of the disease, a case-control study was carried out in Montevideo, Uruguay. Eight hundred and one patients were interviewed, including 252 certified cases of BC and 549 frequency-matched controls. Blood groups (ABO, Rh) were obtained from medical records. Multivariate analyses were performed, adjusting for age, selected menstrual and reproductive factors, and family history of BC as well as of other cancers. We found that the absence of Rh factor (Rh-) was positively associated with the risk of BC (adjusted Odds Ratio [OR]=1.49, 95% Confidence Interval [95% CI] 1.05-2.11). Stratified analyses by family history of BC showed a strong association for Rh- with a positive history of first degree relatives (OR=3.17, 95% CI 1.06-9.47). Also stratified analyses by family history of other cancers showed a positive association for Rh- with a positive history of first degree relatives (OR=2.08, 95% CI 1.05-4.11). Regarding the implications of an inherited factor like Rh and its associations with the family history of BC, it might increase the probability to generate high-risk individuals if further studies confirm the present preliminary findings.

    Although patients with invasive papillary carcinoma (IPC) often have favorable prognoses, it remains unclear whether this special type of breast cancer represents a distinct morphological entity with its own biological features and clinical behavior distinct from those of invasive ductal carcinoma (IDC) and whether its four molecular subtypes are associated with different prognoses. The study is a retrospective analysis of a large patient cohort from a single institution. 284 IPC samples were collected from January 2000 to May 2011. 300 IDC cases were selected randomly from 13,428 cases of IDC during the same periods. We assessed the clinicopathologic characteristics, molecular features, and prognostic value of IPC (n = 284) and compared them to those of IDC (n = 300). Clinicopathologic features and survival status of the four subtypes of IPC were also evaluated. IPC differed from IDC with respect to age upon diagnosis, tumor grade, lymph node status, and menopausal status (P IPC was associated with a better 5-year overall survival rate (OS) (92.77 vs. 87.95 %) and disease-free survival rate (DFS) (87.95 vs. 80.72 %) than IDC. Tumors of the luminal A subtype had a better 5-year OS (97.78 %) and DFS (95.56 %) than other subtypes. The biologic behavior of IPC is more favorable to patient outcome than that of IDC. The chance of pure IPC causing death without an intervening event of a different histologic type is exceptionally low. Luminal A subtypes have better outcomes when compared to the other subtypes.

    Full Text Available In order to analyze detailed anthropometric characterisation for risk of breast cancer (BC in premenopausal Uruguayan women, a case-control study was carried out at the Pereira Rossell Women’s Hospital, Montevideo, where 253 incident BC cases and 497 frequency-matched healthy controls were interviewed on menstrual and reproductive story, and a series of body measurements were performed to calculate body composition and somatotype. Odds ratio (OR’s coefficients were taken as estimates of relative risk derived from unconditional logistic regression. Results show a positive association for the fat fraction (OR for highest quartile =4.19, 95% CI (95% Confidence Interval 2.70-6.50 as well as for the fat-to-muscle ratio (OR=4.68, 95% CI 2.98-7.36. Muscle fraction was inversely associated with risk (OR=0.53 95% CI 0.36-0.78. High endomorphism was the only somatotype variable associated to the disease risk (OR=1.69, 95% CI 1.13-2.54, however, losing its association when fat amount was included in the regression model. Stratified analyses by body mass index (BMI levels, bone weight, age groups and number of live births also showed risk increases for the highest fat fractions, displaying significant linear trends. Albeit most of the literature reports a putative slight protective effect for a high BMI in premenopausal women, our results suggest that fat fraction, amount and distribution might play a role as predisposing factors for premenopausal BC.

    Breast cancer is the most common cancer in women worldwide. Biology contributes to the early diagnosis and monitoring of breast cancer with several categories of markers such as prognostic markers (ER, PR, HER2), proliferative markers (Ki67), and tumor markers such as CEA and CA 15-3. CEA can be detected at a high concentration in serum of patients with malignant tumors. The aim of our study was to evaluate the concentrations of CEA in serum of women with breast cancer and to verify the existence of a possible link between the average rates of CEA and SBR grade. Serum samples from 100 patients with breast cancer and 100 controls was recovered and examined with an AxSYM analyzer (Abbott Laboratories, USA) to measure CEA using Microparticle Enzyme Immunoassay (MEIA) technology. In our clinical study, the mean age of patients and controls were 52.7 and 50.3 years respectively. The results revealed an elevation in the CEA levels from patients with an average value of 16.61 ± 0.2 ng/ml. Positive correlation was found between CEA concentrations and SBR grade, it has found with 45,7 ± 1 ng/ml in grade III. CEA represents an excellent marker for breast cancer development. Changes in its concentration reflect the effectiveness or ineffectiveness of treatment.

  13. Myiasis associated with an invasive ductal carcinoma of the left breast: case study

    Full Text Available ABSTRACT Most breast cancers originate in the ductal epithelium and are referred to as invasive ductal carcinoma. In this study we report on the clinical procedures adopted to diagnose myiasis in association with infiltrating metastatic breast carcinoma in a female patient. A 41 years old woman came to the Federal Hospital of Andaraí complaining of intense itching, warmth, redness and hardening of the breast, which had acquired the aspect of an orange peel. A lesion in the left breast was cavitated, dimpled, had fetid odor, and had fibrotic and infected air nodules filled with exudate and Dipteran larvae. The tissue was cleaned and 33 larvae were extracted. The patient was hospitalized and received Ivermectin. Eighteen of the larvae extracted from the patient were placed in 70% alcohol, and twelve were placed in a container with sterile wood shavings under controlled conditions until they metamorphosed into adults. The taxonomic identification of the flies revealed that the culprit was Cochliomyia hominivorax. A histopathological exam conducted three months earlier had revealed infiltrating ductal carcinoma. Two months after the myiasis treatment, the breast tissue had healed. The patient had waited ten days from the onset of the myiasis to seek treatment, and that delay interfered negatively in the prognosis of both the neoplasm and the myiasis. This study is relevant to public health in view of the strong social impact of myiasis.

    Several epidemiologic studies have reported a positive association between breast cancer risk and high intake of sweets, which may be due to an insulin-related mechanism. We investigated this association in a population-based case-control study of 1434 cases and 1440 controls from Long Island, NY. Shortly after diagnosis, subjects were interviewed in-person to assess potential breast cancer risk factors, and self-completed a modified Block food frequency questionnaire (FFQ), which included 11 items pertaining to consumption of sweets (sweet beverages, added sugars and various desserts) in the previous year. Using unconditional logistic regression models, we estimated the association between consumption of sweets and breast cancer. Consumption of a food grouping that included dessert foods, sweet beverages and added sugars was positively associated with breast cancer risk [adjusted odds ratio (OR) comparing highest to lowest quartile: 1.27, 95% confidence interval (CI): 1.00-1.61]. The OR was slightly higher when only dessert foods were considered (OR: 1.55, 95% CI: 1.23-1.96). The association with desserts was stronger among premenopausal women (OR: 2.00, 95% CI: 1.32-3.04) than postmenopausal women (OR: 1.40, 95% CI: 1.07-1.83), although the interaction with menopause was not statistically significant. Our study indicates that frequent consumption of sweets, particularly desserts, may be associated with an increased risk of breast cancer. These results are consistent with other studies that implicate insulin-related factors in breast carcinogenesis. PMID:19387852

    The level of total adiponectin, a mixture of different adiponectin forms, has been reported associated with breast cancer risk with inconsistent results. Whether the different forms play different roles in breast cancer risk prediction is unclear. To examine this, we measured total and high molecular weight (HMW) adiponectin in a case-control study (1167 sets). Higher circulating HMW adiponectin was negatively associated with breast cancer risk after adjusting for menopausal status and family history of breast cancer (P=0.024). We analyzed the relationship between adiponectin and breast cancer risk in 6 subgroups. Higher circulating HMW adiponectin was also negatively associated with breast cancer risk (P=0.020, 0.014, 0.035) in the subgroups of postmenopausal women, negative family history of breast cancer, BMI>=24.0. Total adiponectin was positively associated with breast cancer (P=0.028) in the subgroup of BMItotal adiponectin ratio was negatively associated with breast cancer (P=0.019) in the subgroup of postmenopausal women. Interestingly, in the subgroup of women with family history of breast cancer, higher circulating total and HMW adiponectin were positively associated with breast cancer risk (P=0.034, 0.0116). This study showed different forms of circulating adiponectin levels might play different roles in breast cancer risk. A higher circulating HMW adiponectin is associated with a decreased breast cancer risk, especially in postmenopausal, without family history of breast cancer or BMI>=24.0 subgroups, whereas higher circulating HMW adiponectin levels is a risk factor in women with a family history of breast cancer. Further investigation of different forms of adiponectin on breast cancer risk is needed.

  17. [Osteogenesis imperfecta and breast carcinoma. A case study of radiobiological interest].

    Osteogenesis imperfecta (OI) is an inherited disorder of connective tissue with abnormal quality and/or quantity of type 1 collagen. The frequency of the association of OI and breast cancer as well as the frequency of radiation induced side-effects in patients with OI are not known. Certain diseases with widespread collagen alterations such as systemic lupus erythematodes or dermatomyositis--although not exactly comparable to congenital OI--carry a high risk for radiation injuries in case of irradiation with normal doses. The report of a patient with osteogenesis imperfecta type I and postmastectomy irradiation might therefore be of some radiobiological interest. Report of a 46-year-old women with OI type I and breast cancer with a 14-year follow-up time after mastectomy and external beam irradiation. During all the follow-up time there was no radiation injury in this patient with OI type I and breast cancer. Mostly it is not possible to draw a valid conclusion from a case report, but with this experience the combination of OI type I and radiotherapy seems not to cause unusual radiation injury. Contrary to OI of type II and III, in the majority of the cases of OI type I there is a normal quality, but diminished quantity of collagen type I. This could be one of the possible reasons for the absence of adverse radiation effects. Finally, it might be of interest, that the gene-locus of the two alpha-1(I)-chains of collagen type I is situated at chromosome 17q21-22, where also the location of the "breast-cancer gene" is supposed to be. A genetic examination was, unfortunately, refused by the patient.

    The purpose of this study was to test the hypothesis that multigenotypic polymorphisms in the folate metabolic pathway, which may result in genomic instability and inbalance of estrogen metabolism, were associated with breast cancer risk. A population-based nested case-control study of 109 cases with pathologically confirmed invasive breast cancer and 421 cancer-free controls was conducted in Taiwan between 1992 and 2001. The polymorphisms in serine hydroxymethyltransferase (SHMT1 C1420T), 5,10-methylenetetrahydrofolate reductase (MTHFR C677T), and methionine synthase (MS A2756G) genes were examined using polymerase chain reaction-restriction fragment length polymorphism. There was a trend toward an increased risk of breast cancer in women harboring a greater number of putative high-risk genotypes of these genes. Furthermore, the cancer risk associated with having at least one putative high-risk genotype was more significant in women having been exposed to estrogen for a longer period before first birth. The present study indicates the significance of multiple low-penetrance alleles of functionally-related folate-metabolizing genes interactive with an estrogenic environment in breast tumorigenesis.

    Previous studies have shown that reproductive factors are differentially associated with breast cancer (BC) risk by subtypes. The aim of this study was to investigate associations between reproductive factors and BC subtypes, and whether these vary by age at diagnosis. We used pooled data on tumor markers (estrogen and progesterone receptor, human epidermal growth factor receptor-2 (HER2)) and reproductive risk factors (parity, age at first full-time pregnancy (FFTP) and age at menarche) from 28,095 patients with invasive BC from 34 studies participating in the Breast Cancer Association Consortium (BCAC). In a case-only analysis, we used logistic regression to assess associations between reproductive factors and BC subtype compared to luminal A tumors as a reference. The interaction between age and parity in BC subtype risk was also tested, across all ages and, because age was modeled non-linearly, specifically at ages 35, 55 and 75 years. Parous women were more likely to be diagnosed with triple negative BC (TNBC) than with luminal A BC, irrespective of age (OR for parity = 1.38, 95% CI 1.16-1.65, p = 0.0004; p for interaction with age = 0.076). Parous women were also more likely to be diagnosed with luminal and non-luminal HER2-like BCs and this effect was slightly more pronounced at an early age (p for interaction with age = 0.037 and 0.030, respectively). For instance, women diagnosed at age 35 were 1.48 (CI 1.01-2.16) more likely to have luminal HER2-like BC than luminal A BC, while this association was not significant at age 75 (OR = 0.72, CI 0.45-1.14). While age at menarche was not significantly associated with BC subtype, increasing age at FFTP was non-linearly associated with TNBC relative to luminal A BC. An age at FFTP of 25 versus 20 years lowered the risk for TNBC (OR = 0.78, CI 0.70-0.88, p < 0.0001), but this effect was not apparent at a later FFTP. Our main findings suggest that parity is associated with TNBC across

    Growing but limited evidence suggests that night shift work is associated with breast cancer. The authors conducted a nationwide case-control study nested within a cohort of 18,551 female military employees born in 1929-1968 to investigate the risk for breast cancer after night shift work and to explore the role of leisure time sun exposure and diurnal preference. The authors documented 218 cases of breast cancer (1990-2003) and selected 899 age-matched controls from the cohort by incidence density sampling. Information on shift work, sun exposure habits, diurnal preference and other potential confounders was obtained from a structured questionnaire. ORs were estimated by multivariate conditional logistic regression. Overall, the authors observed an adjusted OR of 1.4 (95% CI 0.9 to 2.1) among women with ever compared with never night shifts. The RR for breast cancer tended to increase with increasing number of years of night shift work (p=0.03) and with cumulative number of shifts (p=0.02),with a neutral risk for fewer than three night shifts per week. The OR for the group with the highest tertile of cumulative exposure was 2.3 (95% CI 1.2 to 4.6). The most pronounced effect of night shift work on breast cancer risk was observed in women with morning chronotype preference and intense night shifts (OR=3.9, 95% CI 1.6 to 9.5). Night shift workers tended to sunbathe more frequently than day workers. The results indicate that frequent night shift work increases the risk for breast cancer and suggest a higher risk with longer duration of intense night shifts. Women with morning preference who worked on night shifts tended to have a higher risk than those with evening preference.

    Full Text Available Functional neuroimaging is an innovative but at this stage underutilized method to assess the efficacy of psychotherapy for depression. Functional magnetic resonance imaging (fMRI was used in this case study to examine changes in brain activity in a depressed breast cancer patient receiving an 8-session Behavioral Activation Treatment for Depression (BATD, based on the work of Hopko and Lejuez (2007. A music listening paradigm was used during fMRI brain scans to assess reward responsiveness at pre- and posttreatment. Following treatment, the patient exhibited attenuated depression and changes in blood oxygenation level dependence (BOLD response in regions of the prefrontal cortex and the subgenual cingulate cortex. These preliminary findings outline a novel means to assess psychotherapy efficacy and suggest that BATD elicits functional brain changes in areas implicated in the pathophysiology of depression. Further research is necessary to explore neurobiological mechanisms of change in BATD, particularly the potential mediating effects of reward responsiveness and associated brain functioning.

    MicroRNAs (miRNAs) are small, non-coding RNA molecules involved in post-transcriptional gene regulation and have recently been shown to play a role in cancer metastasis. In solid tumors, especially breast cancer, alterations in miRNA expression contribute to cancer pathogenesis, including metastasis. Considering the emerging role of miRNAs in metastasis, the identification of predictive markers is necessary to further the understanding of stage-specific breast cancer development. This is a retrospective analysis that aimed to identify molecular biomarkers related to distant breast cancer metastasis development. A retrospective case cohort study was performed in 64 breast cancer patients treated during the period from 1998-2001. The case group (n = 29) consisted of patients with a poor prognosis who presented with breast cancer recurrence or metastasis during follow up. The control group (n = 35) consisted of patients with a good prognosis who did not develop breast cancer recurrence or metastasis. These patient groups were stratified according to TNM clinical stage (CS) I, II and III, and the main clinical features of the patients were homogeneous. MicroRNA profiling was performed and biomarkers related to metastatic were identified independent of clinical stage. Finally, a hazard risk analysis of these biomarkers was performed to evaluate their relation to metastatic potential. MiRNA expression profiling identified several miRNAs that were both specific and shared across all clinical stages (p ≤ 0.05). Among these, we identified miRNAs previously associated with cell motility (let-7 family) and distant metastasis (hsa-miR-21). In addition, hsa-miR-494 and hsa-miR-21 were deregulated in metastatic cases of CSI and CSII. Furthermore, metastatic miRNAs shared across all clinical stages did not present high sensitivity and specificity when compared to specific-CS miRNAs. Between them, hsa-miR-183 was the most significative of CSII, which miRNAs combination for CSII

  4. Genetic Polymorphisms in Vitamin D Metabolism and Signaling Genes and Risk of Breast Cancer: A Nested Case-Control Study.

    Full Text Available Genetic polymorphisms in vitamin D metabolism and signaling genes have been inconsistently associated with risk of breast cancer, though few studies have examined SNPs in vitamin D-related genes other than the vitamin D receptor (VDR gene and particularly have not examined the association with the retinoid X receptor alpha (RXRA gene which may be a key vitamin D pathway gene. We conducted a nested case-control study of 734 cases and 1435 individually matched controls from a population-based prospective cohort study, the Northern Sweden Mammary Screening Cohort. Tag and functional SNPs were genotyped for the VDR, cytochrome p450 24A1 (CYP24A1, and RXRA genes. We also genotyped specific SNPs in four other genes related to vitamin D metabolism and signaling (GC/VDBP, CYP2R1, DHCR7, and CYP27B1. SNPs in the CYP2R1, DHCR7, and VDBP gene regions that were associated with circulating 25(OHD concentration in GWAS were also associated with plasma 25(OHD in our study (p-trend <0.005. After taking into account the false discovery rate, these SNPs were not significantly associated with breast cancer risk, nor were any of the other SNPs or haplotypes in VDR, RXRA, and CYP24A1. We observed no statistically significant associations between polymorphisms or haplotypes in key vitamin D-related genes and risk of breast cancer. These results, combined with the observation in this cohort and most other prospective studies of no association of circulating 25(OHD with breast cancer risk, do not support an association between vitamin D and breast cancer risk.

    There is limited evidence that the gestational age at delivery may influence the risk of maternal breast cancer. While extreme prematurity has been suggested to increase the risk, there seems to be no study available so far that investigates the due effects of a late delivery. This research aimed to identify the impact of both preterm and late deliveries on the risk of maternal breast cancer within a period of 5 years after birth. Our dataset was created by linking data from the Nevada Cancer Registry database (1995-2008) and the birth certificates issued by the Nevada State Health Division (1994-2003). The study cohort consisted of 213,250 women who gave birth from January 1, 1994 to December 31, 2003. We performed a nested population-based case-control study on 126 Nevada mothers with a first lifetime breast cancer diagnosed from January 1, 1995 through December 31, 2003, and 504 Nevada cancer-free mothers. Women with pregnancies who progressed beyond 40 weeks of gestation were at a significantly lower risk of developing breast cancer for the 5-year period following a delivery, when compared to women who delivered at 37-40 weeks of gestation (OR: 0.33, 95% CI: 0.11-0.92) in a multivariate model. Additional pregnancy characteristics did not significantly predict the risk of maternal breast cancer. Pregnancies that extended beyond 40 weeks of gestation were strongly associated with a lower likelihood of premenopausal breast cancer. Biological plausibility for this association may correspond to the fact that as pregnancy develops into more advanced stages, mammary cells have more time to attain complete differentiation and maturation; a process that starts early in the third trimester. © 2016 Wiley Periodicals, Inc.

    Literature has identified detrimental health effects from the indiscriminate use of artificial nighttime light. We examined the co-distribution of light at night (LAN) and breast cancer (BC) incidence in Georgia, with the goal to contribute to the accumulating evidence that exposure to LAN increases risk of BC. Using Georgia Comprehensive Cancer Registry data (2000-2007), we conducted a case-referent study among 34,053 BC cases and 14,458 lung cancer referents. Individuals with lung cancer were used as referents to control for other cancer risk factors that may be associated with elevated LAN, such as air pollution, and since this cancer type was not previously associated with LAN or circadian rhythm disruption. DMSP-OLS Nighttime Light Time Series satellite images (1992-2007) were used to estimate LAN levels; low (0-20 watts per sterradian cm(2)), medium (21-41 watts per sterradian cm(2)), high (>41 watts per sterradian cm(2)). LAN levels were extracted for each year of exposure prior to case/referent diagnosis in ArcGIS. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using logistic regression models controlling for individual-level year of diagnosis, race, age at diagnosis, tumor grade, stage; and population-level determinants including metropolitan statistical area (MSA) status, births per 1,000 women aged 15-50, percentage of female smokers, MSA population mobility, and percentage of population over 16 in the labor force. We found that overall BC incidence was associated with high LAN exposure (OR = 1.12, 95% CI [1.04, 1.20]). When stratified by race, LAN exposure was associated with increased BC risk among whites (OR = 1.13, 95% CI [1.05, 1.22]), but not among blacks (OR = 1.02, 95% CI [0.82, 1.28]). Our results suggest positive associations between LAN and BC incidence, especially among whites. The consistency of our findings with previous studies suggests that there could be fundamental biological links between exposure to artificial LAN

    Full Text Available Abstract Background Although it is believed that fish ω-3 fatty acids may decrease breast cancer risk, epidemiological evidence has been inconclusive. This study examined the association between fish and fish ω-3 fatty acids intake with the risk of breast cancer in a case-control study of Korean women. Methods We recruited 358 incident breast cancer patients and 360 controls with no history of malignant neoplasm from the National Cancer Center Hospital between July 2007 and April 2008. The study participants were given a 103-item food intake frequency questionnaire to determine their dietary consumption of fish (fatty and lean fish and ω-3 fatty acids derived from fish (eicosapentaenoic acid (EPA, and docosahexaenoic acid (DHA. Results Using a multivariate logistic regression model, high intake of fatty fish was associated with a reduced risk for breast cancer in both pre- and postmenopausal women (OR [95% CI] for highest vs. lowest intake quartiles, p for trend: 0.19 [0.08 to 0.45], p p = 0.005 for postmenopausal women. Similarly, reductions in breast cancer risk were observed among postmenopausal subjects who consumed more than 0.101 g of EPA (OR [95% CI]: 0.38 [0.15 to 0.96] and 0.213 g of DHA (OR [95% CI]: 0.32 [0.13 to 0.82] from fish per day compared to the reference group who consumed less than 0.014 g of EPA and 0.037 g of DHA per day. Among premenopausal women, there was a significant reduction in breast cancer risk for the highest intake quartiles of ω-3 fatty acids (ORs [95% CI]: 0.46 [0.22 to 0.96], compared to the reference group who consumed the lowest quartile of intake. Conclusion These results suggest that high consumption of fatty fish is associated with a reduced risk for breast cancer, and that the intake of ω-3 fatty acids from fish is inversely associated with postmenopausal breast cancer risk.

    While several risk factors for breast cancer have been identified, studies have not consistently shown whether these factors operate more strongly at certain ages or for just pre- or postmenopausal women. We evaluated whether risk factors for breast cancer differ according to age or menopausal status. Data from five population-based case-control studies conducted during 1988-2008 were combined and analyzed. Cases (N = 23,959) and population controls (N = 28,304) completed telephone interviews. Logistic regression was used to estimate adjusted odds ratios and 95 % confidence intervals and tests for interaction by age and menopausal status. Odds ratios for first-degree family history of breast cancer were strongest for younger women-reaching twofold elevations-but were still statistically significantly elevated by 58-69 % among older women. Obesity was inversely associated with breast cancer among younger women and positively associated with risk for older women (interaction P breast cancer risk among older women, although consumption of 3 or more drinks/day among younger women also was associated with elevated odd ratios (P breast disease and most reproductive/menstrual factors did not vary by age. Repeating analysis stratifying by menopausal status produced similar results. With few exceptions, menstrual and lifestyle factors are associated with breast cancer risk regardless of age or menopausal status. Variation in the association of family history, obesity, and alcohol use with breast cancer risk by age and menopausal status may need to be considered when determining individual risk for breast cancer.

    Metaplastic carcinoma of the breast (MCB) is a rare histological subtype of breast cancer with an incidence of less than 0.1%-0.5%. Due to its rarity, the clinical characteristics and prognostic significance of MCB compared with other common breast cancers (like infiltrating ductal carcinoma [IDC], and infiltrating lobular carcinoma [ILC]) are not clear, and controversial among different reports. We performed a collective comparison study of multi-institutional cases to evaluate the clinical characteristics and prognostic status of MCB to compare with IDC and ILC. A case control analysis was performed to minimize the bias from clinicopathologic factors between IDC and MCB. Disease free survival (DFS) and overall survival (OS) between groups were compared. Forty-five MCB patients were enrolled from the 4 medical centers and compared with 1777 IDC and 53 ILC patients from the CCH cancer registry database comprise the current study. Compared with IDC, MCB was associated with older age, larger tumor size, a lesser lymph node positive rate, a higher likelihood of distant metastasis, higher tumor grade, lower ER-positive tumor, and higher triple negative breast cancer subtype (TNBC). MCB was associated with worse OS (p = 0.031) than IDC, but no difference in DFS (p = 0.071); however, MCB was not statistically different from ILC in both DFS and OS (p = 0.289 and 0.132, respectively). Compared with the case-controlled IDC group, MCB patients had poorer OS (p = 0.040), but no difference in DFS (p = 0.439). MCB is associated with poorer OS than IDC, and this was related to tumor behavior rather than clinicopathologic factors. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available The evidence on the relationship between breast cancer and different types of antihypertensive drugs taken for at least 5 years is limited and inconsistent. Furthermore, the debate has recently been fueled again with new data reporting an increased risk of breast cancer among women with a long history of use of antihypertensive drugs compared with nonusers.In this case-control study, we report the antihypertensive drugs-breast cancer relationship in 1,736 breast cancer cases and 1,895 healthy controls; results are reported stratifying by the women's characteristics (i.e., menopausal status or body mass index category tumor characteristics and length of use of antihypertensive drugs.The relationship among breast cancer and use of calcium channel blockers (CCB for 5 or more years had odds ratio (OR = 1.77 (95% CI, 0.99 to 3.17. Stratifying by BMI, the OR increased significantly in the group with BMI ≥ 25 (OR 2.54, 95% CI, 1.24 to 5.22. CCBs were even more strongly associated with more aggressive tumors, (OR for invasive tumors = 1.96, 95% CI = 1.09 to 3.53; OR for non ductal cancers = 3.97, 95% CI = 1.73 to 9.05; OR for Erbb2+ cancer = 2.97, 95% CI: 1.20 to 7.32. On the other hand, premenopausal women were the only group in which angiotensin II receptor blockers may be associated with breast cancer (OR = 4.27, 95% CI = 1.32 to 13.84 but this could not be identified with any type or stage. Use of angiotensin-converting-enzyme inhibitors, beta blockers and diuretics were not associated with risk.In this large population-based study we found that long term use of calcium channel blockers is associated with some subtypes of breast cancer (and with breast cancer in overweight women.

    Breast Phyllodes tumors are rare breast tumors present in less than 1% of new cases of breast cancer, usually occurring among middle-aged women (40-50 yrs). This study shows diagnostic experience, surgical management and follows up of patients with this disease during a period of ten years in a oncology referral center. Retrospectively, breast cancer registries at the institution were reviewed, identifying 77 patients with Phyllodes tumors between 2002 and 2012, who had been operated on at the Instituto de Cancerología - Clínica Las Américas, in Medellín (Colombia). Clinical and histopathological data belonging to these cases was captured and analyzed and descriptive statistics were used. The follow up median was 22.5 months (IQR: 10.5-60.0), average age was 47.2 yrs (SD: 12.4), mean tumor size was 3.6 cm (SD: 4.6), 88.3% of the patients (68 cases) presented negative margins and none of them received adjuvant chemotherapy. Of the patients with Phyllodes tumors; 33.8% had benign, 31.2% had borderline and 35.0% had malignant tumor. Disease-free survival was 85.8% and overall survival was 94.5%. Reported data in this article is in accordance with what has been reported in worldwide literature. In our cohort even the high mean size of the tumors, the risk of local relapse and metastatic disease is low than previously reported in literature. Trials with longer follow up and molecular trials in Phyllodes tumors are necessary to understand the behavior of these tumors in Hispanics population.

    Muhammad Usman Rashid

    Full Text Available Vitamin D is postulated to decrease the risk of breast cancer by inhibiting cell proliferation via the vitamin D receptor (VDR. Two common single nucleotide polymorphisms (SNPs in the VDR gene, rs1544410 (BsmI and rs2228570 (FokI, are inconsistently associated with breast cancer risk in Caucasian populations, while data for Asians are scarce. Here, we investigated the possible contribution of these SNPs to breast cancer risk in Pakistani breast cancer patients and in controls participating in a hospital-based breast cancer case-control study (PAK-BCCC.Genotyping of the BsmI and FokI SNPs was performed by PCR-based restriction fragment length polymorphism (RFLP analysis of 463 genetically enriched female breast cancer cases with known BRCA1/2 status and in 1,012 controls from Pakistan. The association between SNP genotypes and breast cancer risk was investigated by logistic regression adjusted for potential breast cancer risk factors and stratified by BRCA1/2 status and family history. Odds ratios (ORs and 95% confidence intervals (CIs were reported.The b allele of the BsmI was associated with an increased breast cancer risk (per b allele OR 1.28, 95% CI 1.09-1.49, P = 0.003. Subgroup analysis revealed that this effect was restricted to BRCA1/2 non-carriers (per b allele OR 1.33, 95% CI 1.11-1.59, P = 0.002 and was stronger in those who reported a positive family history of breast and/or ovarian cancer (per b allele OR 1.64, 95% CI 1.20-2.22, P = 0.002. No association with breast cancer risk was detected for the FokI SNP.The BsmI polymorphism in the VDR gene may be associated with an increased breast cancer risk in Pakistani women negative for BRCA1/2 germline mutations.

    Mammographic density is a strong risk factor for breast cancer, but its potential application in risk management is not clear, partly due to uncertainties about its interaction with other breast cancer risk factors. We aimed to quantify the impact of mammographic density on breast cancer risk in women aged 40-49 at intermediate familial risk of breast cancer (average lifetime risk of 23%), in particular in premenopausal women, and to investigate its relationship with other breast cancer risk factors in this population. We present the results from a case-control study nested with the FH01 cohort study of 6,710 women mostly aged 40-49 at intermediate familial risk of breast cancer. One hundred and three cases of breast cancer were age-matched to one or two controls. Density was measured by semiautomated interactive thresholding. Absolute density, but not percent density, was a significant risk factor for breast cancer in this population after adjusting for area of nondense tissue (OR per 10 cm(2) = 1.07, 95% CI 1.00-1.15, p = 0.04). The effect was stronger in premenopausal women, who made up the majority of the study population. Absolute density remained a significant predictor of breast cancer risk after adjusting for age at menarche, age at first live birth, parity, past or present hormone replacement therapy, and the Tyrer-Cuzick 10-year relative risk estimate of breast cancer. Absolute density can improve breast cancer risk stratification and delineation of high-risk groups alongside the Tyrer-Cuzick 10-year relative risk estimate. © 2014 UICC.

    Délio Marques Conde

    Full Text Available CONTEXT: Supernumerary breast tissue may be affected by the same diseases and alterations that compromise topical breast tissue. Nevertheless, reports of fibroadenoma in supernumerary breast tissue in the axillae are rare. OBJECTIVE: To describe a case of fibroadenoma in an axillary supernumerary breast. DESIGN: Case report. CASE REPORT: A 39-year-old woman was referred to the gynecology and obstetrics outpatient clinic at Hospital Estadual Sumaré, complaining of bilateral axillary masses. The patient reported cosmetic problems and local pain and discomfort. On physical examination, alterations compatible with bilateral axillary accessory breasts, without palpable nodules, were observed. Supplementary examinations (mammography and ultrasonography revealed a 1.1 cm mass in the right axillary breast. The patient underwent resection of the supernumerary breasts and histopathological examination revealed fibroadenoma of the right axillary breast tissue.

    The purpose of this study was to assess the role of coping and defending mechanisms as a risk factor for breast cancer. Women with breast symptoms were referred by physicians to the Kuopio University Hospital (Finland) and were asked to participate in this study. The women (n=115) were interviewed and all study variables were obtained before any diagnostic procedures were done, so neither the investigator nor the subject knew the final diagnosis of breast symptoms at the time of the interview. The research method used was the semistructured in-depth interview method. The investigator used the Montgomery-Asberg Depression rating scale (MADRS) to evaluate the depression of the study subjects. All study subjects were also asked to complete standardised questionnaires (Beck Depression Inventory and Spielberger Trait Inventory). The investigator used the modified coping and defence inventory made by Haan. This inventory is divided into ten scales, and each scale has subscales from grade 0 to grade 3. In addition, the researcher estimated the patients ability to cope (scale 1 to 5), the amount of defensiveness (scale 1 to 5) and fragmentation (scale 1 to 5). Clinical examination and biopsy showed breast cancer (BC) in 34 patients, benign breast disease (BBD) in 53 patients, while 28 study subjects were healthy (HSS). The results indicated that breast cancer patients used more defending mechanisms; denial, intellectualising, rationalisation and reaction formation than the BBD and HSS groups. The defensive mechanisms were significantly associated with increased breast cancer risk (RR=1.7, CI=1.1-2.6). In addition, the breast cancer patients used less coping mechanisms; concentration, intellectuality, logical analysis, empathy, ambiguity tolerance, regression-ego, sublimation and substitution. The results of this study support a moderate association between unsatisfactory coping and defending mechanisms and increased breast cancer risk. The biological explanation of the

    Full Text Available Today, tamoxifen is one of the world's best-selling hormonal breast cancer drugs. However, it was not always so. Compound ICI 46,474 (as it was first known was synthesized in 1962 within a project to develop a contraceptive pill in the pharmaceutical laboratories of ICI (now part of AstraZeneca. Although designed to act as an anti-estrogen, the compound stimulated, rather than suppressed ovulation in women. This, and the fact that it could not be patented in the USA, its largest potential market, meant that ICI nearly stopped the project. It was saved partly because the team's leader, Arthur Walpole, threatened to resign, and pressed on with another project: to develop tamoxifen as a treatment for breast cancer. Even then, its market appeared small, because at first it was mainly used as a palliative treatment for advanced breast cancer. An important turning point in tamoxifen's journey from orphan drug to best-selling medicine occurred in the 1980s, when clinical trials showed that it was also useful as an adjuvant to surgery and chemotherapy in the early stages of the disease. Later, trials demonstrated that it could prevent its occurrence or re-occurrence in women at high risk of breast cancer. Thus, it became the first preventive for any cancer, helping to establish the broader principles of chemoprevention, and extending the market for tamoxifen and similar drugs further still. Using tamoxifen as a case study, this paper discusses the limits of the rational approach to drug design, the role of human actors, and the series of feedback loops between bench and bedside that underpins pharmaceutical innovation. The paper also highlights the complex evaluation and management of risk that are involved in all therapies, but more especially perhaps in life-threatening and emotion-laden diseases like cancer.

    Full Text Available Bilateral synchronous male breast cancer is very rare. A 63-year-old male presented with rapidly progressive enlarging bilateral breast masses without ulceration and bloody nipple discharge. Synchronous bilateral breast cancer was diagnosed by fine needle aspiration cytology. Pathology study revealed grade 2 invasive ductal carcinoma in both breasts. He underwent a bilateral modified radical mastectomy followed by chemotherapy and hormone therapy. The importance of this case report is to create increased attention to the fact that, although rare, breast cancer can occur in males. Early presentation and compliance with treatment modality provide a better outcome.

    One of the hallmarks of cancer is the occurrence of high levels of chromosomal rearrangements as a result of inaccurate repair of double-strand breaks (DSB). Germline mutations in BRCA and RAD51 genes, involved in DSB repair, are strongly associated with hereditary breast cancer. Pol θ, a translesional DNA polymerase specialized in the replication of damaged DNA, has been also shown to contribute to DNA synthesis associated to DSB repair. It is noteworthy that POLQ is highly expressed in breast tumors and this expression is able to predict patient outcome. The objective of this study was to analyze genetic variants related to POLQ as new population biomarkers of risk in hereditary (HBC) and sporadic (SBC) breast cancer. We analyzed through case-control study nine SNPs of POLQ in hereditary (HBC) and sporadic (SBC) breast cancer patients using Taqman Real Time PCR assays. Polymorphisms were systematically identified through the NCBI database and are located within exons or promoter regions. We recruited 204 breast cancer patients (101 SBC and 103 HBC) and 212 unaffected controls residing in Southern Brazil. The rs581553 SNP located in the promoter region was strongly associated with HBC (c.-1060A > G; HBC GG = 15, Control TT = 8; OR = 5.67, CI95% = 2.26-14.20; p Hereditary Breast and Ovarian Cancer (HBOC) syndrome. Furthermore, 12 of them developed bilateral breast cancer and one had a familial history of bilateral breast cancer. This polymorphism was also associated with bilateral breast cancer in 67 patients (OR = 9.86, CI95% = 3.81-25.54). There was no statistically significant difference of age at breast cancer diagnosis between SNP carriers and non-carriers. Considering that Pol θ is involved in DBS repair, our results suggest that this polymorphism may contribute to the etiology of HBC, particularly in patients with bilateral breast cancer.

    Background: The role of vitamin D in breast cancer prevention is equivocal. Saudi Arabian women may be at greater risk of vitamin D deficiency because of a darker skin type and a greater likelihood of reduced ultraviolet B radiation exposure. Data regarding the vitamin D status of Saudi Arabian women and its relation to breast cancer risk are lacking.

    Breast cancer is recognized as a major public health problem in developing countries; however, there is very little evidence of behavioral factors associated with breast cancer risk. This study was conducted to identify lifestyles as risk factors for breast cancer among Central African women. A case-control study was conducted with 174 cases confirmed histologically by the pathology unit of the National Laboratory and 348 age-matched controls. Data collection tools included a questionnaire with interviews and medical records of patients. Data were analyzed using SPSS software version 20. Odd ratio (OR) and 95% confidence intervals (95% CI) were obtained by unconditional logistic regression. In total, 522 women were studied with a mean age of 45.8 (SD = 13.4) years. By unconditional logistic regression model, women with breast cancer were more likely to have attained illiterate and elementary education level [11.23 (95% CI, 4.65–27.14) and 2.40 (95% CI, 1.15–4.99)], married [2.09 (95% CI, 1.18–3.71)], positive family history [2.31 (95% CI, 1.36–3.91)], radiation exposure [8.21 (95% CI, 5.04–13.38)], consumption charcuterie [10.82 (95% CI, 2.39–48.90)], fresh fish consumption [4.26 (95% CI, 1.56–11.65)], groundnut consumption [6.46 (95% CI, 2.57–16.27)], soybean consumption [16.74 (95% CI, 8.03–39.84)], alcohol [2.53 (95% CI, 1.39–4.60)], habit of keeping money in bras[3.57 (95% CI, 2.24–5.69)], overweight [5.36 (95% CI, 4.46–24.57)] and obesity [3.11(95% CI, 2.39–20.42)]. However, decreased risk of breast cancer was associated with being employed [0.32 (95% CI, 0.19–0.56)], urban residence [0.16 (95% CI, 0.07–0.37)], groundnut oil consumption [0.05 (95% CI, 0.02–0.14)], wine consumption [0.16 (95% CI, 0.09–0.26)], non habit of keeping cell phone in bras [0.56 (95% CI, 0.35–0.89)] and physical activity [0.71(95% CI, 0.14–0.84)].

    Concerns about breast cancer overdiagnosis have increased the need to understand how cancers detected through screening mammography differ from those first detected by a woman or her clinician. We investigated risk factor associations for invasive breast cancer by method of detection within a series of case-control studies (1992-2007) carried out in Wisconsin, Massachusetts, and New Hampshire (n=15,648 invasive breast cancer patients and 17,602 controls aged 40-79 years). Approximately half of case women reported that their cancer had been detected by mammographic screening and half that they or their clinician had detected it. In polytomous logistic regression models, parity and age at first birth were more strongly associated with risk of mammography-detected breast cancer than with risk of woman/clinician-detected breast cancer (P≤0.01; adjusted for mammography utilization). Among postmenopausal women, estrogen-progestin hormone use was predominantly associated with risk of woman/clinician-detected breast cancer (odds ratio (OR)=1.49, 95% confidence interval (CI): 1.29, 1.72), whereas obesity was predominantly associated with risk of mammography-detected breast cancer (OR=1.72, 95% CI: 1.54, 1.92). Among regularly screened premenopausal women, obesity was not associated with increased risk of mammography-detected breast cancer (OR=0.99, 95% CI: 0.83, 1.18), but it was associated with reduced risk of woman/clinician-detected breast cancer (OR=0.53, 95% CI: 0.43, 0.64). These findings indicate important differences in breast cancer risk factors according to method of detection. © The Author 2015.

    Hansen, Johnni; Stevens, Richard G

    2012-07-01

    Working outside normal daytime hours is increasing worldwide and is now one of the most widespread potential carcinogenic occupational exposures. There is sufficient evidence in experimental animals that light exposure during the biologic night increases tumour growth and limited epidemiologic evidence that night shift-work cause breast cancer. Existing studies had crude definitions of shift-work and did not discriminate between shift-work systems (e.g. permanent versus rotating or evening versus night). We performed an interview based nested case-control study within a nationwide cohort of Danish nurses, including detailed information on lifetime shift-work and potential confounders. Cases of primary breast cancer (n=310) were identified from the nationwide Danish Cancer Registry. Four control nurses were selected for each case by incidence density sampling. Odds rations (ORs) and 95% confidence intervals (CIs) were estimated by conditional logistic regression, with adjustment for potential confounders. Overall, nurses who worked rotating shifts after midnight had a significantly increased OR (1.8; CI 1.2-2.8) for breast cancer compared to nurses with permanent day work. No association was found in a small group of nurses with evening work and no night work (OR=0.9; 0.4-1.9). The subgroup of nurses with periods of permanent night shift in addition to rotating night and day shifts experienced an OR of 2.9 (1.1-8.0). For nurses working after midnight compared to nurses never ending work before midnight, OR in the third tertile of cumulative number of shifts was 2.2 (1.5-3.2). In an analysis of different rotating shift systems, the highest OR (2.6; 1.8-3.8) was observed for long-term day-night rotating shifts. The results provide further evidence that night shift-work may increase the risk for breast cancer and suggest that the largest impact on risk is associated with the most disruptive shifts.

    Several studies have shown the effect of dietary patterns on breast cancer risk, but none has been conducted in Argentina. The aim of this study was to extract dietary patterns from Food Frequency Questioner, to estimate their effect on breast cancer occurrence while taking into account aggregation factors (family history of breast cancer) and to explore the sensitivity of the estimates to changes in the assumptions. A principal component exploratory factor analysis was applied to identify dietary patterns, which were then included as covariates in a multilevel logistic regression. Family history of BC was considered as a clustering variable. A multiple probabilistic sensitivity analysis was also performed. The study included 100 cases and 294 controls. Four dietary patterns were identified. Traditional (fat meats, bakery products, and vegetable oil and mayonnaise) (OR III tertile vs I 3.13, 95% CI 2.58-3.78), Rural (processed meat) (OR III tertile vs I 2.02, 95% CI 1.21-3.37) and Starchy (refined grains) (OR III tertile vs I 1.82, 95 % CI 1.18-2.79) dietary patterns were positively associated with BC risk, whereas the Prudent pattern (fruit and non-starchy vegetables) (OR III tertile vs I 0.56, 95% CI 0.41-0.77) showed a protective effect. For Traditional pattern, the median bias-adjusted ORs (3.52) were higher than the conventional (2.76). While the Prudent pattern was associated with a reduced risk of BC, Traditional, Rural and Starchy patterns showed a promoting effect. Despite the threats to validity, the nature of associations was not strongly affected.

    Despite similarly low calcium intakes and normal vitamin D status, only some Nigerian children develop nutritional rickets. We hypothesized that mothers with children who had developed rickets might have lower breast-milk calcium concentration than mothers with normal children and compared the breast-milk calcium concentration of mothers who had had children with rickets with those who had not (controls). We collected breast milk from 35 Nigerian mothers who had previously had children with nutritional rickets. For each case mother, we collected breast milk from three matched control mothers at the same stage of lactation (+/-4 weeks) who had had no children with rickets. Data were collected about parity, stage of lactation, and the infant's intake. The mother's bone density was measured. The mean breast milk calcium concentration of mothers of children with rickets (4.30+/-1.24 mmol/L) was less than that of control mothers (4.65+/-1.03 mmol/L; P=0.034 in multivariate regression controlling for duration of lactation and resumption of menses). Forearm bone mineral content was significantly related to breast milk calcium concentration (r=0.20) after adjusting for height, weight, and bone area (P=0.028). Reduced breast-milk calcium concentration may contribute to a reduced calcium intake in infancy and predispose children to nutritional rickets.

    This study was conducted to identify reproductive and dietary factors associated with benign proliferative mammary epithelial cell changes. Subjects were women enrolled in a randomized trial of breast self-examination in Shanghai, China. Women who developed fibrocystic breast conditions classified as nonproliferative (175 women), proliferative (181 women), or proliferative with atypia (33 women) between 1995 and 2000 and 1,070 unaffected trial participants were administered general risk factor and food frequency questionnaires. Conditional logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals. High parity and consumption of fresh fruits and vegetables were more strongly associated with a reduced risk of proliferative and atypical lesions than with nonproliferative conditions. For the fourth quartile of consumption versus the first, odds ratios for lesions diagnosed as nonproliferative, proliferative, and proliferative with atypia were 0.4 (95% confidence interval (CI): 0.2, 0.7), 0.2 (95% CI: 0.1, 0.4), and 0.1 (95% CI: 0.03, 0.5), respectively, for fruit intake and 0.6 (95% CI: 0.3, 1.1), 0.4 (95% CI: 0.2, 0.7), and 0.1 (95% CI: 0.1, 0.9), respectively, for vegetable intake. Reduced but nonsignificant risks in relation to soy products were observed for proliferative and atypical lesions. No single nutrient or botanical family was appreciably more strongly associated with proliferative conditions than with nonproliferative conditions, after results were controlled for total fruit and vegetable consumption. A diet rich in fruits and vegetables may reduce cellular proliferation in the mammary epithelium; this is one mechanism by which such a diet could reduce risk of breast cancer.

    Breast cancer is the most common cancer in morocco women were it occupies the first place in term of incidence and mortality. The aim of the present paper is to evaluate the risk factors associated with a breast cancer in a population of Moroccan women. A case-control study was conducted with population women whose age is less than 40 years during 2008-2010 at the National Institute of Oncology of Rabat. These women were interviewed for Epidemiological information and risk factor for breast cancer. Included in this study were 124 cases and 148 age matched controls. No statistically significant case-control difference was found for the early age of menarche (OR = 2.474; CI 95%: 1.354- 4.521), and family antecedents of first degree of breast cancer (OR = 11.556; 95% CI: 2.548-52.411). However physical activity (OR = 0.507; 95% CI: 0.339 -0.757) early maternity age (OR = 0.212; 95% CI: 0.087 - 0.514), multiparity (OR = 0.742; 95% CI: 0.359 -1.539) and breastfeeding than 6 months (OR = 0.739; 95% CI: 0.357 -1.523) appear as significant protective factors. This study show the criminalization of only part of the known risk factors of breast cancer in this age group and confirms the probable protective role of physical activity and factors related to life reproductive women in our study (early childbearing, multiparity and lactation).

    There is limited research on the association between sedentary behaviour and breast cancer risk, particularly whether sedentary behaviour is differentially associated with premenopausal and postmenopausal breast cancer. We pooled data from 2 case-control studies from Australia and Canada to investigate this association. This pooled analysis included 1762 incident breast cancer cases and 2532 controls. Participants in both studies completed a lifetime occupational history and self-rated occupational physical activity level. A job-exposure matrix (JEM) was also applied to job titles to assess sedentary work. Logistic regression analyses (6 pooled and 12 study-specific) were conducted to estimate associations between both self-reported and JEM-assessed sedentary work and breast cancer risk among premenopausal and postmenopausal women. No association was observed in the 6 pooled analyses, and 10 of the study-specific analyses also showed null results. 2 study-specific analyses provided inconsistent and contradictory results, with 1 showing statistically significant increased risk of breast cancer for self-reported sedentary work among premenopausal women cancer in the Canadian study, and the other a non-significant inverse association between JEM-assessed sedentary work and breast cancer risk among postmenopausal women in the Australian study. While a suggestion of increased risk was seen for premenopausal women in the Canadian study when using the self-reported measure, overall this pooled study does not provide evidence that sedentary work is associated with breast cancer risk.

    There are several validated risk factors for breast cancer. However the legitimacy of elevated fasting blood glucose (FBG) is not well established. This study was designed to assess this parameter as a risk factor for breast cancer among pre- and post-menopausal women. This case-control study was conducted at Department of Biochemistry, University of Karachi from June 2010 to August 2014. Simple random sampling technique was used to collect data of study subjects comprising 175 diagnosed breast cancer patients with positive histopathology from Breast Clinic, surgical unit-1, Civil Hospital, Karachi and 175 healthy controls from various screening programs. Blood samples were analyzed for FBG and serum insulin. FBG, HOMA-IR, systolic and diastolic blood pressure were significantly raised in breast cancer cases when compared to control subjects. Cases and controls were further categorized in to two groups using cutoff value of 110 mg/dl to distinguish subjects into normal fasting glucose (fasting glucose (≥110-≤125 mg/dl) or diabetes (≥126 mg/dl). Odds ratios were found to be 1.57, 2.15 and 1.17 in overall, pre-menopausal and post-menopausal groups, respectively. (all pcancer exists in women having elevated fasting blood glucose levels, corresponding to prediabetes and diabetes, among pre and postmenopausal ages, with comparatively greater effects in the premenopausal group.

    Recent research from the United Kingdom (UK) has highlighted some of the differences in breast cancer presentations between women of different ethnic groups. Analysis of a large database showed that Black women of African or Caribbean heritage living in England and Wales are more likely to present with stage 3 or 4 cancer than White British women and less likely to have their cancer detected through screening. In many countries around the world, migrant and cultural minority groups experience social and economic disadvantage and this is reflected in their health outcomes. With world migration at record levels, it is timely to reflect on ethnic disparities and to consider how developed nations can care for their minority groups, which are increasing in number and diversity. These issues and challenges are discussed, using the UK's migrant population and Australia's Indigenous and migrant populations as case studies. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Summary Introduction: Sexual dysfunction is highly prevalent, affecting 40% of the female population. The incidence of such dysfunction is known to be higher among women with malignant breast disease and in patients with depression or anxiety. However, there are few data regarding the prevalence of sexual dysfunction among women with benign breast disease (BBD. Objective: To evaluate the incidence of sexual dysfunction, depression and anxiety among women with BBD, in comparison with that observed for healthy women. Method: We evaluated the incidence of sexual dysfunction in 60 patients with benign breast disease (fibroadenomas, breast cysts, breast pain and phyllodes tumor and 69 healthy women (control group. Participants completed the Sexual Quotient Questionnaire for Females (SQQ-F, the Beck Depression Inventory and the Beck Anxiety Inventory. Statistical analysis revealed that depression and anxiety were comparable between BBD and control groups (10.3 vs. 20.3% and 38.7 vs. 34.3%, respectively, p>0.05. The mean SQQ-F score (65.6±22.7 vs. 70.1±16.8; p>0.05 and sexual dysfunction (33.3 vs. 25.4%; p=0.324 were similar between BBD and control groups. Conclusion: We found no differences between women with BBD and healthy women in terms of the incidence of sexual dysfunction, anxiety and depression. Nevertheless, given the high prevalence of this condition, it is important to assess sexual quality of life, as well as overall quality of life, in women with BBD.

    Treatment of breast cancer during pregnancy (BCP) remains a challenge to physicians. Surgery and chemotherapy during pregnancy are widely used for the treatment of BCP. Herein, we reported 3 Chinese patients with BCP who underwent chemotherapy during pregnancy and were followed up for adverse effects. Three female patients (case 1, case 2, and case 3) of 37-, 32-, and 28-year-old with breast masses were enrolled. Case 1 had been pregnant for over 4 months, case 2 over 7 months, and case 3 for 7 months. Ultrasound findings revealed a mass in the left breast in cases 1 and 2 (30 mm × 26 mm × 23 mm and 34 mm × 16 mm × 40 mm), and case 3 had 2 masses in the outer upper quadrant of right breast (27 mm × 27 mm × 26 mm, 18 mm × 17 mm × 17 mm) and 2 fixed enlarged lymph nodes in the right axillary fossa, respectively. All breast masses were diagnosed by core needle biopsy, and the result was infiltrating ductal carcinoma. Chemotherapy regimen administered during pregnancy was EwP (epirubicin 80 mg/m, d1 + paclitaxel 80 mg/m, d1, 8, 15, and cycled every 21 days). During pregnancy, case 1 received 5 cycles, case 2 received 1 cycle, and case 3 received 2 cycles. Case 2 patient experienced grade III bone marrow suppression once. Electrocardiogram (ECG) result of case 3 showed occasional occurrence of ventricular premature beats, with no complaint of discomfort. All 3 patients experienced uterine contractions, which caused preterm labor in case 2. Adverse events were nausea, hair loss, acid reflux, and constipation. Neonatal jaundice occurred in the premature infant (case 2), which was resolved by phototherapy. No relapse or metastasis was observed in the 3 cases and the infants are growing normally. Both patients and infants well tolerated the combination chemotherapy of epirubicin and paclitaxel during pregnancy. There were few drug toxicities and adverse effects.

    Apocrine carcinoma is a rare breast cancer and its frequency is about 0.4% of all breast cancers. Little is known about its clinical behavior and prognosis. To our knowledge, few studies have reported the radiologic appearances of apocrine carcinoma in the breast and there has been no such report from Korea. We describe the sonographic findings of a case of apocrine carcinoma in the breast. The sonographic findings are microlobulated heterogeneous hypoechoic lesion that has a central markedly hypoechoic portion and a peripheral mixture of iso and hypoechgenecity.

    Full Text Available BACKGROUND Breast carcinoma is the most common malignant tumour and the leading cause of death in women worldwide. It accounts for 15% of all cancer deaths in women. According to the World Health Organization (WHO, approximately 70% of breast cancers occur in women with none of the known risk factors. MATERIALS AND METHODS The study population comprised patients of carcinoma breast attending to surgical op and admitted in surgical units 1, 2, 3, 4, 5, 6 at Government General Hospital, Kakinada during November 2013 to November 2015. RESULTS Most common in females, breast lump is most common presentation, increased incidence in postmenopausal women, urban population has a higher incidence, upper outer quadrant is most commonly involved. CONCLUSION In our study, higher incidence is found in 5 th decade, mostly in postmenopausal women from urban areas, most commonly located in upper outer quadrant.

    The procoagulant state in cancer increases the thrombotic risk, but also supports tumor progression. To investigate the molecular mechanisms controlling cancer and hemostasis, we conducted a case-control study of genotypic and phenotypic variables of the tissue factor (TF) pathway of coagulation in breast cancer. 366 breast cancer patients and 307 controls were genotyped for SNPs (n = 41) in the F2, F3 (TF), F5, F7, F10, TFPI and EPCR genes, and assayed for plasma coagulation markers (thrombin generation, activated protein C (APC) resistance, D-dimer, antithrombin, protein C, protein S, and TF pathway inhibitor (TFPI)). Associations with breast cancer were evaluated using logistic regression to obtain odds ratios (ORs) and 95% confidence intervals (CIs), or the chi-square test. Four SNPs in F5 (rs12120605, rs6427202, rs9332542 and rs6427199), one in F10 (rs3093261), and one in EPCR (rs2069948) were associated with breast cancer. EPCR rs2069948 was associated with estrogen receptor (ER) and progesterone receptor (PR) positivity, while the SNPs in F5 appeared to follow hormone receptor negative and triple negative patients. The prothrombotic polymorphisms factor V Leiden (rs6025) and prothrombin G20210A (rs1799963) were not associated with breast cancer. High APC resistance was associated with breast cancer in both factor V Leiden non-carriers (OR 6.5, 95% CI 4.1-10.4) and carriers (OR 38.3, 95% CI 6.2-236.6). The thrombin parameters short lag times (OR 5.8, 95% CI 3.7-9.2), short times to peak thrombin (OR 7.1, 95% CI 4.4-11.3), and high thrombin peak (OR 6.1, 95% CI 3.9-9.5) predicted presence of breast cancer, and high D-dimer also associated with breast cancer (OR 2.0, 95% CI 1.3-3.3). Among the coagulation inhibitors, low levels of antithrombin associated with breast cancer (OR 5.7, 95% CI 3.6-9.0). The increased coagulability was not explained by the breast cancer associated SNPs, and was unaffected by ER, PR and triple negative status. A procoagulant

    Mammographic density is strongly and consistently associated with breast cancer risk. To determine if this association was modified by reproductive factors (parity and age at first birth), data were combined from four case-control studies conducted in the United States and Japan. To overcome the issue of variation in mammographic density assessment among the studies, a single observer re-read all the mammograms using one type of interactive thresholding software. Logistic regression was used to estimate odds ratios (OR) while adjusting for other known breast cancer risk factors. Included were 1,699 breast cancer cases and 2,422 controls, 74% of whom were postmenopausal. A positive association between mammographic density and breast cancer risk was evident in every group defined by parity and age at first birth (OR per doubling of percent mammographic density ranged between 1.20 and 1.39). Nonetheless, the association appeared to be stronger among nulliparous than parous women (OR per doubling of percent mammographic density = 1.39 vs. 1.24; P interaction = 0.054). However, when examined by study location, the effect modification by parity was apparent only in women from Hawaii and when examined by menopausal status, it was apparent in postmenopausal, but not premenopausal, women. Effect modification by parity was not significant in subgroups defined by body mass index or ethnicity. Adjusting for mammographic density did not attenuate the OR for the association between parity and breast cancer risk by more than 16.4%, suggesting that mammographic density explains only a small proportion of the reduction in breast cancer risk associated with parity. In conclusion, this study did not support the hypothesis that parity modifies the breast cancer risk attributed to mammographic density. Even though an effect modification was found in Hawaiian women, no such thing was found in women from the other three locations.

    The C677T polymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene has been hypothesized to increase breast cancer risk. However, results have been inconsistent, and few studies have reported the association by menopausal status or by intakes of nutrients participating in one-carbon metabolism. Our aims were to investigate whether MTHFR C677T was associated with postmenopausal breast cancer risk and whether this relation was modified by intakes of folate, methionine, vitamins B(2), B(6), and B(12), and alcohol. We studied 318 incident breast cancer cases and 647 age- and race-matched controls participating in a nested case-control study of postmenopausal women within the VITamins And Lifestyle (VITAL) cohort. Genotyping was conducted for MTHFR C677T and dietary and supplemental intakes were ascertained from a validated questionnaire. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated using unconditional logistic regression. We observed a 62% increased risk of breast cancer among postmenopausal women with the TT genotype (OR = 1.62; 95% CI: 1.05 to 2.48). Women with a higher number of variant T alleles had higher risk of breast cancer (P for trend = 0.04). Evidence of effect-modification by intakes of some B vitamins was observed. The most pronounced MTHFR-breast cancer risks were observed among women with the lowest intakes of dietary folate (P for interaction = 0.02) and total (diet plus supplemental) vitamin B(6) (P for interaction = 0.01), with no significant increased risks among women with higher intakes. This study provides support that the MTHFR 677TT genotype is associated with a moderate increase in risk of postmenopausal breast cancer and that this risk may be attenuated with high intakes of some one-carbon associated nutrients.

    Full Text Available During pregnancy breast cancer is rarely seen. In this case, when the patient was being operated for the right breast cancer which was diagnosed in the first exam, a left breast cancer was also detected in the operation. When the patient analysed retrospectively, lesion in the left breast could not detected because of the lactation period. Consequently,pregnancy patients must be re-examined after the lactation period to avoid any possible mistakes. [Cukurova Med J 2013; 38(3.000: 492-494

    Catalase (CAT) activity is likely to be affected by functional polymorphism of C-262 T (rs1001179) in the CAT gene (OMIM: 115500). It is hypothesized that individuals with the lower expressing forms of the CAT polymorphism may be more susceptible to breast cancer. Therefore, the present case-control study and meta-analysis were carried out. The present case-control study consisted of 407 females with breast cancer and a total of 395 healthy female from population matched with patients according to age. Genotypic analysis for the CAT C-262 T polymorphism was determined by PCR. We identified 7 eligible studies, including 10,471 subjects (4,959 patients, and 5,512 healthy controls) in relation to the CAT C-262 T polymorphism and breast cancer risk. Based on the present case-control study, the CT (OR = 0.90, 95% CI: 0.66-1.22, P = 0.484) and TT (OR = 0.68, 95% CI: 0.35-1.30, P = 0.245) genotypes were not associated with breast cancer risk compared to the CC genotype. For meta-analysis including all studies, there was significant heterogeneity between studies. The overall ORs of the breast cancer risk were not associated with the CT (Q-statistic = 14.90, df = 6, P 0.05; OR = 1.03, 95% CI: 0.85-1.24, P = 0.770) genotypes. There was no association between C-262 T polymorphism of the CAT and risk of breast cancer.

The aim of the present study was to evaluate the association between adherence to nutrition-based guidelines for cancer prevention and prostate, breast and colorectal cancer, in the MCC-Spain case-control study. A total of 1,718 colorectal, 1,343 breast and 864 prostate cancer cases and 3,431 population-based controls recruited between 2007 and 2012, were included in the present study. The World Cancer Research Fund/American Institute for Cancer Research (WCRC/AICR) score based on six recommendations for cancer prevention (on body fatness, physical activity, foods and drinks that promote weight gain, plant foods, animal foods and alcoholic drinks; score range 0-6) was constructed. We used unconditional logistic regression analysis adjusting for potential confounders. One-point increment in the WCRF/AICR score was associated with 25% (95% CI 19-30%) lower risk of colorectal, and 15% (95% CI 7-22%) lower risk of breast cancer; no association with prostate cancer was detected, except for cases with a Gleason score ≥7 (poorly differentiated/undifferentiated tumours) (OR 0.87, 95% CI 0.76-0.99). These results add to the wealth of evidence indicating that a great proportion of common cancer cases could be avoided by adopting healthy lifestyle habits. © 2017 UICC.

    To investigate the association between post-diagnostic beta-blocker usage and risk of cancer-specific mortality in a large population-based cohort of female breast cancer patients. A nested case-control study was conducted within a cohort of breast cancer patients identified from cancer registries in England(using the National Cancer Data repository) and diagnosed between 1998 and 2007. Patients who had a breast cancer-specific death(ascertained from Office of National Statistics death registration data) were each matched to four alive controls by year and age at diagnosis. Prescription data for these patients were available through the Clinical Practice Research Datalink. Conditional logistic regression models were used to investigate the association between breast cancer-specific death and beta-blocker usage. Post-diagnostic use of beta-blockers was identified in 18.9% of 1435 breast cancer-specific deaths and 19.4% of their 5697 matched controls,indicating little evidence of association between beta-blocker use and breast cancer-specific mortality [odds ratio (OR) = 0.97,95% confidence interval (CI) 0.83, 1.13]. There was also little evidence of an association when analyses were restricted to cardio non-selective beta-blockers (OR = 0.90, 95% CI 0.69, 1.17). Similar results were observed in analyses of drug dosage frequency and duration, and beta-blocker type. In this large UK population-based cohort of breast cancer patients,there was little evidence of an association between post-diagnostic beta-blocker usage and breast cancer progression. Further studies which include information on tumour receptor status are warranted to determine whether response to beta-blockers varies by tumour subtypes.

    Background Early age at first birth and multiparity reduce the risk of estrogen receptor and progesterone receptor (ERPR) positive breast cancer, whereas breastfeeding reduces the risk of both ERPR-positive and ERPR-negative cancers. Methods We used multivariable logistic regression analysis to investigate whether age at first birth (parity on risk of ERPR-positive and ERPR-negative cancer using 1457 incident breast cancer cases and 1455 controls aged ≥ 55 years who participated in the Women's Contraceptive and Reproductive Experiences Study. Results Women who gave birth before age 25 years had a 36% reduced risk of breast cancer compared to nulligravida that was not observed for women who started their families at an older age (P heterogeneity=0.0007). This protective effect was restricted to ERPR-positive breast cancer (P heterogeneity=0.004). Late age at first birth increased the risk of ERPR-negative cancers. Additional births reduced the risk of ERPR-positive cancers among women with an early first birth (P trend=0.0001) and among women who breastfed (P trend=0.004), but not among older mothers or those who never breastfed. In women with a late first birth who never breastfed, multiparity was associated with increased risk of breast cancer. Conclusions These findings suggest that the effect of parity on a woman's long-term risk of breast cancer is modified by age at first full-term pregnancy and possibly by breastfeeding. PMID:18628424

    Full Text Available Background: Breast lump is a very common clinical presentation for which fine needle aspiration cytology is often sought for. Because of it’s significant diagnositic value, FNAC has become a routine tool in the evaluation of the nature of the lesion. The objective of this study was to determine the cytomorphological patterns of breast lump in eastern part of Nepal among individuals attending Nobel Medical College. Materials and Methods: This was a retrospective descriptive study done in department of pathology from December 2012 to June 2015. All individuals presenting with breast lumps was included in this study. FNAC was done as per standard procedure and categorized as per United Kingdom National Health Survey Breast Screening Programme (UK-NHS-BSP categories and further also categorized in to neoplastic and non-neolastic categories. Results: We studied 771 cases of breast lumps. Occurrence of breast lump was more common in female (97.4%. Neoplastic lesions accounted for 84.1% of cases out of which benign comprised of 94.6% and malignant comprised of 5.6%. Common benign lesions observed were that of fibroadenona (264 and fibrocystic changes (204. Ductal carcinoma was the most common malignant lesions. All malignant lesions were observed in older age and female sex population.Conclusion: Most of the cases of breast lumps are benign in nature and very few accounted for malignant cases. There is predominance of benign lesions in young age and increased malignancy in older age and female population.

    Full Text Available Background: Primary leiomyosarcoma (LMS of the breast is a very rare neoplasm of the breast arising from the mesenchymal tissue. The clinical presentation of this entity simulates other benign and malignant lesions of mesenchymal tissue of the breast.Case presentation: Case 1: A 40-year-old female presented with a right-sided breast lump, which was suspected to be a malignant spindle cell tumor on needle core biopsy (NCB. A multi-disciplinary team performed modified radical mastectomy (MRM with axillary node dissection on the patient with no post-operative chemo-radiation. Case 2: A 70-year-old female presented with a left sided breast lump and a palpable axillary node. Needle core biopsy diagnosed it as malignant spindle cell tumor. The patient underwent MRM with axillary node dissection. It was confirmed to be a case of breast LMS with axillary nodal metastasis. Both patients were followed up for one year with no evidence of recurrence.Conclusion: Both cases underwent MRM with axillary node dissection in our study. However, the role of axillary dissection in the prognosis and disease-free survival of the patients with primary LMS of the breast with axillary metastasis has not been studied yet. The optimal management of this entity remains to be tumor excision with clear margins.

    Mammographic density has been shown to be a strong independent predictor of breast cancer and a causative factor in reducing the sensitivity of mammography. There remain questions as to the use of mammographic density information in the context of screening and risk management, and of the association with cancer in populations known to be at increased risk of breast cancer. To assess the association of breast density with presence of cancer by measuring mammographic density visually as a percentage, and with two automated volumetric methods, Quantra™ and VolparaDensity™. The TOMosynthesis with digital MammographY (TOMMY) study of digital breast tomosynthesis in the Breast Screening Programme of the National Health Service (NHS) of the United Kingdom (UK) included 6020 breast screening assessment cases (of whom 1158 had breast cancer) and 1040 screened women with a family history of breast cancer (of whom two had breast cancer). We assessed the association of each measure with breast cancer risk in these populations at enhanced risk, using logistic regression adjusted for age and total breast volume as a surrogate for body mass index (BMI). All density measures showed a positive association with presence of cancer and all declined with age. The strongest effect was seen with Volpara absolute density, with a significant 3% (95% CI 1-5%) increase in risk per 10 cm 3 of dense tissue. The effect of Volpara volumetric density on risk was stronger for large and grade 3 tumours. Automated absolute breast density is a predictor of breast cancer risk in populations at enhanced risk due to either positive mammographic findings or family history. In the screening context, density could be a trigger for more intensive imaging. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Breast cancer is a major cause of morbidity and mortality in Jordan and worldwide. Abnormality of DNA methylation is a possible mechanism for the development of cancer. Methylenetetrahydrofolate reductase (MTHFR) is involved in DNA methylation. Our aim was to study the association between genetic polymorphisms of MTHFR at two sites (C677T and A1298C) and their haplotypes and the risk of breast cancer among Jordanian females. A case-control study involving 150 breast cancer cases and 150 controls was conducted. Controls were age-matched to cases. Polymerase chain reaction/restriction fragment length polymorphism (PCR-RFLP) technique and sequencing were conducted to determine the genotypes. There was a significant difference in genotype frequency of C677T in the 41-60 year age category [cases: CC (37.4%), CT (49.5%) and TT (13.2%); controls: CC (56.3%), CT (35.6%) and TT (8%), p=0.04; ORTT vs. CC: 2.5, 95% CI: (0.9-6.9); ORat least on T: 2.1, 95%CI: (1.2-3.9)]. There was no significant difference in genotype frequency of A1298C between cases and controls [cases: AA (46.6%), AC (41.8%) and CC (11.6%); controls: AA (43%), AC (47.4%) and CC (9.6%); p=0.6]. There was a significant difference of MTHFR genetic polymorphism haplotypes among breast cancer cases and controls [cases/control: CA: 38.3/45.4%; CC: 28.9/25.2%; TA: 29.2/21; TC: 3.6/8.3; p value=0.01; ORTA vs. CA=1.6; 95% CI (1.1-2.5); p=0.02]. Genetic polymorphism of MTHFR C677T may modulate the risk of breast cancer especially in the 41-60 year age group. Additionally, TA haplotype amends the risk of breast cancer. Future studies with a larger sample size are needed to validate the role of MTHFR genetic polymorphisms in breast cancer.

    The relation between suicidal ideation versus hopelessness/helplessness in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared to date in a prospective study. We, therefore, investigated suicidal ideation versus hopelessness/helplessness in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness versus suicidal/pessimistic thoughts before any diagnostic procedures were carried-out. In the self-rating score (SRS), hopelessness and the helplessness versus pessimistic thoughts were significantly correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa-values for hopelessness versus pessimistic thoughts in the BBD group were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) in the hopelessness versus pessimistic thoughts in the HSS, BBD and BC groups, as well as in the ERS, in the helplessness versus pessimistic thoughts in the HSS and BBD groups. In SRS, the hopelessness and the helplessness versus suicidal thoughts were significantly correlated in the HSS, BBD and BC groups. There was also a significant positive correlation in the ERS in the hopelessness versus suicidal thoughts in the HSS, BBD and BC groups, as well as in the ERS, in the helplessness versus suicidal thoughts in the BBD group. A new finding with clinical relevance in the present work is the agreement between hopelessness/helplessness versus suicidal/pessimistic thoughts in the self-rating and examiner-rating. In the breast cancer diagnostic Unit, the identification of suicidal ideation is essential in suicide prevention and it is important to assess and treat depression even though a subject reports little suicidal ideation.

    Two main research efforts in early detection of breast cancer include the development of software tools to assist radiologists in identifying abnormalities and the development of training tools to enhance their skills. Medical image analysis systems, widely known as Computer-Aided Diagnosis (CADx) systems, play an important role in this respect. Often it is important to determine whether there is a benefit in including computer-processed images in the development of such software tools. In this paper, we investigate the effects of computer-processed images in improving human performance in ultrasound breast cancer detection (a perceptual task) and classification (a cognitive task). A survey was conducted on a group of expert radiologists and a group of non-radiologists. In our experiments, random test images from a large database of ultrasound images were presented to subjects. In order to gather appropriate formal feedback, questionnaires were prepared to comment on random selections of original images only, and on image pairs consisting of original images displayed alongside computer-processed images. We critically compare and contrast the performance of the two groups according to perceptual and cognitive tasks. From a Receiver Operating Curve (ROC) analysis, we conclude that the provision of computer-processed images alongside the original ultrasound images, significantly improve the perceptual tasks of non-radiologists but only marginal improvements are shown in the perceptual and cognitive tasks of the group of expert radiologists.

    Alcohol consumption and mammographic density are established risk factors for breast cancer. This study examined whether the association of mammographic density with breast cancer varies by alcohol intake. Mammographic density was assessed in digitized images for 1207 cases and 1663 controls from three populations (Japan, Hawaii, California) using a computer-assisted method. Associations were estimated by logistic regression. When comparing ever to never drinking, mean density was similar and consumption was not associated with breast cancer risk. However, within the Hawaii/Japan subset, women consuming >1 drink/day had a non-significantly elevated relative risk compared to never drinkers. Also in the Hawaii/Japan population, alcohol intake only modified the association between mammographic density and breast cancer in women consuming >1 drink/day (p(interaction)=0.05) with significant risk estimates of 3.65 and 6.58 for the 2nd and 3rd density tertiles as compared to 1.57 and 1.61 for never drinkers in Hawaii/Japan. Although these findings suggest a stronger association between mammographic density and breast cancer risk for alcohol consumers, the small number of cases requires caution in interpreting the results.

    The purpose of this analysis was to compare disease-free survival (DFS), progression-free survival (PFS), and overall survival (OS) between pregnant and nonpregnant patients with breast cancer. From 1989 to 2009, 75 women were treated with chemotherapy during pregnancy. Each pregnant case was matched on age and cancer stage to two nonpregnant patients with breast cancer (controls). Fisher's exact test, the Kaplan-Meier method, and Cox proportional hazards regression models were used. Median follow-up time for patients who were alive at the end of follow-up (n = 159) was 4.20 years (range: 0.28-19.94 years). DFS at 5 years was 72% (95% confidence interval [CI]: 58.3%-82.1%) for pregnant patients and 57% (95% CI: 46.7%-65.8%) for controls (p = .0115). Five-year PFS was 70% (95% CI: 56.8%-80.3%) for pregnant patients and 59% (95% CI: 49.1%-67.5%) for controls (p = .0252). Five-year OS was 77% (95% CI: 63.9%-86.4%) for pregnant patients and 71% (95% CI: 61.1%-78.3%) for controls (p = .0461). Hazard ratio estimates favored improved survival for pregnant patients in univariate analyses and multivariate analyses, controlling for age, year of diagnosis, stage, and tumor grade. For patients who received chemotherapy during pregnancy, survival was comparable to-if not better than-that of nonpregnant women. Pregnant patients with breast cancer should receive appropriate local and systemic therapy for breast cancer.

    To assess the association of smoked meat intake, SULT1A1 polymorphism as well as their combined effects with breast cancer risk. A total of 400 newly diagnosed breast cancer cases from a cancer hospital in Sichuan province and 400 healthy controls from participants of physical examination in a hospital in Chengdu city were recruited from May 2007 to July 2009. A valid questionnaire was designed to collect their demographic characteristics and breast cancer risk factors. Daily intake of foods was collected using semi-quantitative frequency questionnaire and then the daily intake of smoked meat was calculated and transformed to energy-adjusted smoked meat intake by the residual method. Gene sequencing was used to analyze SULT1A1 Arg213His genotypes. Multivariable conditional logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (95%CIs). The energy-adjusted daily intake of smoked meat (Median (P₂₅, P₇₅)) was 8.65 (3.63, 18.44) g/d in cases and 4.44 (0.19, 8.71) g/d in controls. The frequency of SULT1A1 variant allele was 14.75% (59/400) among cases and 12.75% (51/400) among controls. High energy-adjusted daily intake of smoked meat (≥ 4.44 g/d) was significantly associated with breast cancer risk among premenopausal (OR = 2.31, 95%CI: 1.46 - 3.66) and postmenopausal subjects (OR = 3.13, 95%CI: 1.89 - 5.17). High energy-adjusted daily intake of smoked meat combined with carrying SULT1A1 variant allele elevated breast cancer risk among premenopausal (OR = 3.31, 95%CI: 1.66 - 6.62) and postmenopausal subjects (OR = 3.81, 95%CI: 1.79 - 8.10). High smoked meat intake contributes to high risk of breast cancer. SULT1A1 variant allele increases breast cancer risk among subjects who were exposed to high smoked meat intake.

    Breast cancer represents a major public health problem in women worldwide. For many cancers, serum tumour markers play an important role in patient treatment and monitoring. Isocitrate dehydrogenase enzyme is also used as a biomarker for various types of cancer. The purpose of this study was to determine serum Isocitrate dehydrogenase-2 (IDH-2) enzyme activity in breast cancer patients (pre and post chemotherapy) and also correlate the changes in enzyme activity with stages of cancer and control groups. In this case-control study, histologically confirmed 40 female patients aged 28-80 years who fulfilled the criteria for diagnosis of invasive breast cancer were selected in our study groups from surgery outpatient department of SS Hospital, BHU, Varanasi, India, and 40 healthy age matched females were selected between October 2013 to July 2015. The estimation of serum IDH-2 enzyme activity in before and after two cycles of neoadjuvant chemotherapy patients was performed by spectrophotometry assay. The mean serum IDH-2 activity in cases (Mean±SD) was significantly more than control group (pIDH-2 activity in cases was significantly decrease after neo-adjuvant chemotherapy (p=0.019). In stage II pre chemotherapy patients serum IDH-2 activity was higher than post chemotherapy (pIDH-2 activity was not significant (p-value>0.05). The serum IDH-2 can be a potential biomarker in breast carcinoma and can be used for prognosis and monitoring the chemotherapy response of the patients.

    Studies have shown that gene and environmental factors, such as BRCA1/2 mutations, ionized radiation, and chemical carcinogens, are related with breast cancer. X-ray repair cross-complementing group 3 (XRCC3) is involved in homologous repair of double DNA breaks. It was reported that Thr241Met single-nucleotide polymorphism (SNP) in XRCC3 is associated with increased risk of breast cancer. However, the finding remains controversial. The current meta-analysis aims to determine whether XRCC3 Thr241Met polymorphism is associated with increased risk of breast cancer. We performed a meta-analysis of association between XRCC3 T241M polymorphism and the risk of breast cancer. Crude odds ratios (ORs) together with 95% confidence intervals (CIs) were used to assess the strength of association in dominant, recessive, and homozygote models. We included 23 studies consisting of 13513 cases and 14100 controls in our study. For meta-analysis on the entire database, association of the SNP and breast cancer risk was observed in recessive (OR=1.10, 95% CI: 1.03-1.18, p=0.005) and homozygote (OR=1.09, 95% CI: 1.01-1.18, p=0.023) models. For the analysis on the Asian population subgroup, association of the SNP and breast cancer risk was also observed in recessive (OR=1.615, 95% CI: 1.17-2.228, p=0.004) and homozygote (OR=1.609, 95% CI: 1.154-2.241, p=0.005) models. For the evaluation of the patients without family history of breast cancer, association of the SNP and breast cancer risk was observed in dominant (OR=1.364, 95% CI: 1.096-1.698, p=0.005), recessive (OR=1.336, 95% CI: 0.999-1.788, p=0.051) and homozygote (OR=1.492, 95% CI: 1.085-2.051, p=0.014) models. We can conclude that XRCC3 Thr241Met polymorphism might be associated with breast cancer risk, especially in Asian populations and in patients without family history of breast cancer.

    VEGF is a specific mitogen and survival factor for endothelial cells and a key promoter of angiogenesis in physiological and pathological conditions. Nevertheless, VEGF tissue evaluation in cancer patients as a prognostic factor compared to the conventional histological and biological parameters is still controversial. In this case-control study, tissue VEGF was retrospectively determined by immunohistochemistry and related to T, N, ER, PgR, c-erbB-2, p53, MIB-1 and cyclin D1 in 129 breast cancer patients. Seventy-four of these patients had developed distant metastases postoperatively. The remaining 55 patients had remained disease-free >10 years after surgery. In 17 (13%) of the 129 patients (six with distant metastases and eleven disease-free) tissue and plasma VEGF were concomitantly evaluated. In univariate analysis no significant differences in VEGF and tumor size were found between metastatic and disease-free patients, whereas there were significant differences in N, ER, PgR, c-erbB-2, p53, MIB-1 and cyclin D1 (p ranging from 0.001 to 0.0001). In multivariate analysis VEGF showed less significance than N, ER, c-erbB-2, MIB-1 and cyclin D1 (p = 0.012, p = 0.007, p = 0.005, p = 0.005, p = 0.002 and p = 0.001, respectively). VEGF was a significant unfavorable prognostic indicator only in the N+ subset (p = 0.015), while ER (p = 0.05 and p = 0.021) and MIB-1 (p = 0.031 and p = 0.022) were significant in both the N+ and N- subgroups. In multivariate analysis in the 74 metastatic cases VEGF did not show any significance in relation to disease-free interval and overall survival from the time of mastectomy and from the time of relapse, whereas N and PgR did (p ranging from 0.018 to 0.001). In conclusion, tissue VEGF does not seem a suitable candidate to replace conventional histological and other common biological prognostic factors in breast cancer.

    The histological grade/stage of tumor is widely acknowledged as an important clinical prognostic factor for cancer progression. Recent experimental studies have explored the following two topics at the molecular level: (1) whether or not gene expression levels vary by different degrees among different tumor grades/stages, and (2) whether some well-defined modules could distinguish one grade/stage from another. In this article, using breast cancer as an example, we investigated this topic and identified grade/stage-related active modules under the framework of a weighted network integrated from a human protein interaction network and a transcriptional regulatory network. Our results enabled us to draw the conclusion that the gene expression profile could provide more clues about tumor grade, but reveals less evidence about tumor stage. In addition, we found that our modular biomarker method had additional advantages in identifying some tumor grade/stage-related genes with slightly altered expression. According to our case study, the framework we introduced could be used for other cancers to identify their modules during grading or staging.

    Full Text Available Lymphedema is defined as a persistent increase of tissue volume caused by the blocked or absent lymphatic drainage. The purpose of this study is to analyse the effectiveness of lymphatic drainage in the treatment of lymphedema after a mastectomy, with the aim of reducing the volume of the lymphedema and improving overall symptomatology, as well as providing information regarding the impact of this treatment on quality-of-life and the physical limitations of these patients. With these objectives in mind, a series of articles evaluating the effectiveness of manual lymphatic drainage in the case of patients with breast cancer and lymphedema have been studied. The parameters under observation were: duration of lymphedema reduction and improved symptomatology (pain, a feeling of swelling of the upper limb, functional limitation, and patient dissatisfaction towards their body image. Following this analysis, one can conclude that the association of manual lymphatic drainage to physical exercise and physiotherapy has produced changes in the volume of the limb affected by the lymphedema; however, its isolated use has not resulted in significant changes.

    Recall bias is a potential source of misclassification in case-control studies. Studies have shown that the association between exposure and disease can differ according to participants' beliefs or knowledge about the effect of that exposure on disease. We investigated the association between belief about breast cancer causation and self-reported shift work exposure in a case-control study. Women completed a questionnaire asking whether they believed that shift work caused cancer either before or after reporting their history of shift work. We measured: whether belief modified the association between reported shift work and disease; whether belief was associated with reported shift work exposure; and whether being prompted to recall shift work exposure was associated with an increased likelihood of believing that shift work increased breast cancer risk. There was a significant association between believing shift work increased breast cancer risk and reporting exposure to shift work. Being prompted to recall shift work was not associated with a belief that shift work increased risk. The association between pre-existing belief about breast cancer risk and reported shift work is likely to be due to exposed individuals believing that exposure increases risk, rather than resulting from recall bias.

    We have previously shown that a tag single nucleotide polymorphism (rs10235235), which maps to the CYP3A locus (7q22.1), was associated with a reduction in premenopausal urinary estrone glucuronide levels and a modest reduction in risk of breast cancer in women age ≤50 years. We further investigated the association of rs10235235 with breast cancer risk in a large case control study of 47,346 cases and 47,570 controls from 52 studies participating in the Breast Cancer Association Consortium. Genotyping of rs10235235 was conducted using a custom Illumina Infinium array. Stratified analyses were conducted to determine whether this association was modified by age at diagnosis, ethnicity, age at menarche or tumor characteristics. We confirmed the association of rs10235235 with breast cancer risk for women of European ancestry but found no evidence that this association differed with age at diagnosis. Heterozygote and homozygote odds ratios (ORs) were OR = 0.98 (95% CI 0.94, 1.01; P = 0.2) and OR = 0.80 (95% CI 0.69, 0.93; P = 0.004), respectively (P(trend) = 0.02). There was no evidence of effect modification by tumor characteristics. rs10235235 was, however, associated with age at menarche in controls (P(trend) = 0.005) but not cases (P(trend) = 0.97). Consequently the association between rs10235235 and breast cancer risk differed according to age at menarche (P(het) = 0.02); the rare allele of rs10235235 was associated with a reduction in breast cancer risk for women who had their menarche age ≥15 years (OR(het) = 0.84, 95% CI 0.75, 0.94; OR(hom) = 0.81, 95% CI 0.51, 1.30; P(trend) = 0.002) but not for those who had their menarche age ≤11 years (OR(het) = 1.06, 95% CI 0.95, 1.19, OR(hom) = 1.07, 95% CI 0.67, 1.72; P(trend) = 0.29). To our knowledge rs10235235 is the first single nucleotide polymorphism to be associated with both breast cancer risk and age at menarche consistent with the well-documented association between later age at menarche and a reduction in

    Full Text Available Background: Optimization of workflow for breast cancer samples with equivocal human epidermal growth factor receptors 2 (HER2/neu score 2 + results in routine practice, remains to be a central focus of the on-going efforts to assess HER2 status. According to the College of American Pathologists/American Society of Clinical Oncology guidelines equivocal HER2/neu score 2 + cases are subject for further testing, usually by fluorescence in situ hybridization (FISH investigations. It still remains on open question, whether quantitative digital image analysis of HER2 immunohistochemistry (IHC stained slides can assist in further refining the HER2 score 2 + . Aim of this Work: To assess utility of quantitative digital analysis of IHC stained slides and compare its performance to FISH in cases of breast cancer with equivocal HER2 score 2 + . Materials and Methods: Fifteen specimens (previously diagnosed as breast cancer and was evaluated as HER 2– score 2 + represented the study population. Contemporary new cuts were prepared for re-evaluation of HER2 immunohistochemical studies and FISH examination. All the cases were digitally scanned by iScan (Produced by BioImagene [Now Roche-Ventana]. The IHC signals of HER2 were measured using an automated image analyzing system (MECES, www.Diagnomx.eu/meces. Finally, a comparative study was done between the results of the FISH and the quantitative analysis of the virtual slides. Results: Three out of the 15 cases with equivocal HER2 score 2 + , turned out to be positive (3 + by quantitative digital analysis, and 12 were found to be negative in FISH too. Two of these three positive cases proved to be positive with FISH, and only one was negative. Conclusions: Quantitative digital analysis is highly sensitive and relatively specific when compared to FISH in detecting HER2/neu overexpression. Therefore, it represents a potential reliable substitute for FISH in breast cancer cases, which desire further refinement

    There are long-standing interests in the potential benefits of vitamin D for preventing breast cancer recurrence and mortality, yet data from prospective cohort studies are limited. To investigate a serum biomarker of vitamin D status, 25-hydroxyvitamin D (25OHD) measured at the time of breast cancer diagnosis, to determine the association with prognosis. The Pathways Study is a prospective cohort study of breast cancer survivors established in 2006. Enrollment was completed in 2013; follow-up is ongoing. The cohort was established in Kaiser Permanente Northern California, a large integrated health care delivery system in northern California. Women with a diagnosis of incident invasive breast cancer were typically consented and enrolled within 2 months of diagnosis. The overall enrollment rate was 46% (4505 of 9820). Participants are followed for health outcomes and comorbidities at 12, 24, 48, 72, and 96 months after baseline interview. A case-cohort design was used for efficiency assay of 25OHD, selecting 1666 cohort members with serum samples and ensuring representation in the subcohort of races and clinical subtypes. The data analysis was performed from January 5, 2014, to March 15, 2015. Primary outcomes are breast cancer recurrence, second primary cancer, and death. Mean (SD) age was 58.7 (12.4) years. Serum 25OHD concentrations were lower in women with advanced-stage tumors, and the lowest in premenopausal women with triple-negative cancer. Levels were also inversely associated with hazards of disease progression and death. Compared with the lowest tertile, women with the highest tertile of 25OHD levels had superior overall survival (OS). This association remained after adjustment for clinical prognostic factors (hazard ratio [HR], 0.72; 95% CI, 0.54-0.98). Among premenopausal women, the association with OS was stronger, and there were also associations with breast cancer-specific survival and invasive disease-free survival (OS: HR, 0.45; 95% CI, 0

    Bovine leukemia virus (BLV) and human papillomavirus (HPV) were previously identified in human breast tissue and have been associated with breast cancer in independent studies. The objective of the current study was to test for the presence of BLV and HPV in the same breast tissue specimens to determine whether the viruses were associated with breast cancer either singly or together. Archival formalin-fixed paraffin-embedded breast tissue sections from 216 women were received from The University of Texas MD Anderson Cancer Center along with patient diagnosis. In situ polymerase chain reaction and/or DNA hybridization methods were used to detect targeted DNA segments of BLV and HPV. Standard statistical methods were used to calculate age-adjusted odds ratios, attributable risk, and P values for the trend related to the association between presence of a virus and a diagnosis of breast disease. Women diagnosed with breast cancer were significantly more likely to have BLV DNA in their breast tissue compared with women with benign diagnoses and no history of breast cancer. Women with breast pathology classified as premalignant and no history of breast cancer also were found to have an elevated risk of harboring BLV DNA in their breast tissue. HPV status was not associated with malignancy, premalignant breast disease, or the presence of BLV in the breast tissues. The data from the current study supported previous findings of a significant association between BLV DNA in breast tissue and a diagnosis of breast cancer, but did not demonstrate oncogenic strains of HPV associated with breast cancer or the presence of BLV DNA in breast tissue. The authors believe the findings of the current study contribute to overall knowledge regarding a possible causal role for viruses in human breast cancer.

    Breast metastases from extramammary malignancies are uncommon. Although metastatic lesions show variable radiologic features, there have been few reports of metastatic breast cancer with negative sonographic findings. Furthermore, the results of several studies have indicated a high negative predictive value when ultrasonographic and mammographic findings were normal in the setting of a palpable lump, and follow-up is recommended when the physical examination is not highly suspicious. Herein, we report a case of a 26-year-old woman with breast metastasis from a known gastric adenocarcinoma, which had negative findings without any evidence of suspicious features for malignancy on the initial mammogram and ultrasound.

    Full Text Available BACKGROUND: Manganese superoxide dismutase (MnSOD inhibits oxidative damage and cancer therapy effectiveness. A polymorphism in its encoding gene (SOD2: Val16Ala rs4880 may confer poorer breast cancer survival, but data are inconsistent. We examined the association of SOD2 genotype and breast cancer recurrence (BCR among patients treated with cyclophosphamide-based chemotherapy (Cyclo. We compared our findings with published studies using meta-analyses. METHODS: We conducted a population-based case-control study of BCR among women in Jutland, Denmark. Subjects were diagnosed with non-metastatic breast cancer from 1990-2001, received adjuvant Cyclo, and were registered in the Danish Breast Cancer Cooperative Group. We identified 118 patients with BCR and 213 matched breast cancer controls. We genotyped SOD2 and used conditional logistic regression to compute the odds ratio (OR and associated 95% confidence intervals (95% CI of BCR. We used random-effects meta-analytic models to evaluate the association of SOD2 polymorphisms and BCR. RESULTS: The frequency of the SOD2-Ala allele was 70% in cases versus 71% in controls; 40% versus 44% were heterozygotes, and 30% versus 25% were homozygotes, respectively. Heterozygote and homozygote carriers of the Ala allele had no increased rate of BCR (OR = 1.1, 95%CI = 0.65, 2.0, and OR = 0.87, 95%CI = 0.47, 1.6, respectively. Five studies informed the meta-analytic models; summary estimates associating BCR for homozygote, or any inheritance of the variant Ala allele were 1.18 (95%CI = 0.74, 1.88, and 1.18, (95%CI = 0.91, 1.54, respectively. CONCLUSION: Our findings do not suggest that MnSOD enzymatic activity, as measured by SOD2 genotype, affects rates of BCR among patients treated with Cyclo.

    Seventy-four post menopausal patients with primary non-metastatic invasive ductal carcinomas of the breast were first treated with tamoxifen alone (30 mg p.o. daily) for 5 months. To study changes induced by tamoxifen, core biopsies before treatment and surgical specimens after hormonal therapy were assayed by immunohistochemistry for oestrogen (ER) and progesterone receptors (PR), pS2, GSTpi and c-erbB2. After tamoxifen, ER and PR significantly decreased in 60 and 44 cases respectively, whereas 11 and 19 cases showed no variation and 2 and 11 cases showed an increase (P<10(-4)). GSTpi and pS2 showed a significant increase in 43 and 41 cases, a decrease in 2 and 21 cases and no variation in 29 and 12 cases (P<10(-4) and P=0.04 respectively). c-erbB-2 showed no significant variation under tamoxifen, increased in only three cases and decreased in 13 cases. No relation was found between these variations and efficiency of hormone therapy. Our results allow a better knowledge of protein expression modifications occurring in breast cancer cells under tamoxifen therapy. They are also more consistent with clone selection rather than with phenotype modification. Images Figure 1 PMID:8611373

    Early age at first birth and multiparity reduce the risk of estrogen receptor-progesterone receptor (ERPR)-positive breast cancer, whereas breastfeeding reduces the risk of both ERPR-positive and ERPR-negative cancers. We used multivariable logistic regression analysis to investigate whether age at first birth ( or =25 years) and breastfeeding (ever/never) modify the long-term effect of parity on risk of ERPR-positive and ERPR-negative cancer using 1,457 incident breast cancer cases and 1,455 controls ages > or =55 years who participated in the Women's Contraceptive and Reproductive Experiences Study. Women who gave birth before age 25 years had a 36% reduced risk of breast cancer compared with nulligravida that was not observed for women who started their families at an older age (P(heterogeneity) = 0.0007). This protective effect was restricted to ERPR-positive breast cancer (P(heterogeneity) = 0.004). Late age at first birth increased the risk of ERPR-negative cancers. Additional births reduced the risk of ERPR-positive cancers among women with an early first birth (P(trend) = 0.0001) and among women who breastfed (P(trend) = 0.004) but not among older mothers or those who never breastfed. In women with a late first birth who never breastfed, multiparity was associated with increased risk of breast cancer. These findings suggest that the effect of parity on a woman's long-term risk of breast cancer is modified by age at first full-term pregnancy and possibly by breastfeeding.

    Purpose Despite the overlap between the clinical symptoms/sequelae of polycystic ovarian syndrome (PCOS) and many known reproductive risk factors for breast cancer, the relationship between PCOS and breast cancer remains unclear, possibly because of the complex heterogeneity and challenges in diagnosing PCOS over time. We hypothesized that PCOS, specific PCOS-related symptoms/sequelae, or clusters of PCOS-related symptoms/sequelae, may be differentially associated with pre- vs. postmenopausal breast cancer risk. Materials and Methods Cases were 1,508 women newly diagnosed with a first primary in situ or invasive breast, and the 1,556 population-based controls were frequency-matched by age. Results History of physician-diagnosed PCOS was reported by 2.2% (n=67), among whom oral contraceptive (OC) use, irregular menstruation, and infertility due to ovulatory dysfunction were common. Using unconditional logistic regression, adjusted odds ratios (95% confidence intervals) for PCOS were increased for premenopausal [2.74 (1.13, 6.63)], but not post-menopausal breast cancer [0.87 (0.44, 1.71)]. We used cluster analysis to investigate whether risk among all women varied by PCOS-related symptoms/sequelae, such as reproductive irregularities, OC use, and components of insulin resistance. In the cluster analysis, odds ratios were elevated among premenopausal women who had a history of OC use and no ovulatory dysfunction [1.39 (1.03, 1.88)], compared to those with fewer number of PCOS-related symptoms/sequelae. Conclusion PCOS, and associated PCOS-related symptoms/sequelae including OC use, may play a role in the development of premenopausal breast cancer. Our findings require confirmation in studies with a larger number of premenopausal women with systematically applied diagnostic criteria for PCOS. PMID:26797454

    Little is known about the association between tamoxifen usage and risk of Parkinson's disease in women with breast cancer. The present study aimed to evaluate the association between tamoxifen usage and Parkinson's disease in older women with breast cancer in Taiwan. We conducted a retrospective nationwide case-control study using the database of the Taiwan National Health Insurance Program. In total, 293 female subjects with breast cancer, aged 65 years and above, who were newly diagnosed with Parkinson's disease between 2000 and 2011 were included. Additionally, 1053 female subjects with breast cancer aged 65 years and above without Parkinson's disease were randomly selected as controls. Both cases and controls were matched for age and comorbidities. Ever use of tamoxifen was defined as subjects who had at least a prescription for tamoxifen before the index date, whereas never use of tamoxifen was defined as those who never had a prescription for tamoxifen before the index date. We used the unconditional logistic regression model to calculate the odds ratio (OR) and 95% confidence interval (CI) for the association between tamoxifen usage and risk of Parkinson's disease. After adjusting for confounding variables, the adjusted OR of Parkinson's disease was 3.32 for subjects with ever use of tamoxifen (95% CI, 2.50-4.43), compared with nonusers. Further analysis showed that the adjusted ORs of Parkinson's disease were 3.21 (95% CI, 2.29-4.49), 3.95 (95% CI, 2.77-5.64), and 11.4 (95% CI, 2.63-49.7) for subjects with Parkinson's disease among older women with breast cancer in Taiwan.

    Previous studies suggest that polycyclic aromatic hydrocarbons (PAHs) may adversely affect breast cancer risk. Indoor air pollution from use of indoor stoves and/or fireplaces is an important source of ambient PAH exposure. However, the association between indoor stove/fireplace use and breast cancer risk is unknown. We hypothesized that indoor stove/fireplace use in a Long Island, New York study population would be positively associated with breast cancer and differ by material burned, and the duration and timing of exposure. We also hypothesized that the association would vary by breast cancer subtype defined by p53 mutation status, and interact with glutathione S-transferases GSTM1, T1, A1 and P1 polymorphisms. Population-based, case-control resources (1,508 cases/1,556 controls) were used to conduct unconditional logistic regression to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI). Breast cancer risk was increased among women reporting ever burning synthetic logs (which may also contain wood) in their homes (OR = 1.42, 95% CI 1.11, 1.84), but not for ever burning wood alone (OR = 0.93, 95% CI 0.77, 1.12). For synthetic log use, longer duration >7 years, older age at exposure (>20 years; OR = 1.65, 95% CI 1.02, 2.67) and 2 or more variants in GSTM1, T1, A1 or P1 (OR = 1.71, 95% CI 1.09, 2.69) were associated with increased risk. Burning wood or synthetic logs are both indoor PAH exposure sources; however, positive associations were only observed for burning synthetic logs, which was stronger for longer exposures, adult exposures, and those with multiple GST variant genotypes. Therefore, our results should be interpreted with care and require replication.

    Full Text Available Abstract Background To date, few epidemiologic studies have examined the relationship between environmental PCDD/F exposure and breast cancer in human populations. Dioxin emissions from municipal solid waste incinerators (MSWIs are one of the major sources of environmental dioxins and are therefore an exposure source of public concern. The purpose of this study was to examine the association between dioxins emitted from a polluting MSWI and invasive breast cancer risk among women residing in the area under direct influence of the facility. Methods We compared 434 incident cases of invasive breast cancer diagnosed between 1996 and 2002, and 2170 controls randomly selected from the 1999 population census. A validated dispersion model was used as a proxy for dioxin exposure, yielding four exposure categories. The latter were linked to individual places of residence, using Geographic Information System technology. Results The age distribution at diagnosis for all cases combined showed a bimodal pattern with incidence peaks near 50 and 70 years old. This prompted us to run models separately for women aged 20–59 years, and women aged 60 years or older. Among women younger than 60 years old, no increased or decreased risk was found for any dioxin exposure category. Conversely, women over 60 years old living in the highest exposed zone were 0.31 time less likely (95% confidence interval, 0.08–0.89 to develop invasive breast cancer. Conclusion Before speculating that this decreased risk reflects a dioxin anti-estrogenic activity with greater effect on late-onset acquired breast cancer, some residual confounding must be envisaged.

    The development of breast cancer is multifactorial. Hormonal, environmental factors and genetic predisposition, among others, could interact in the presentation of breast carcinoma. Human leukocyte antigen (HLA) alleles play an important role in immunity (cellular immunity) and may be important genetic traits. HLAAllele-specific interaction has not been well established. Recently, several studies had been conducted in order to do so, but the results are controversial and in some instances contradictory. We designed a case-control study to quantify the association of HLA class I and II genes and breast cancer. HLA typing was performed by high resolution sequence-specific oligotyping after DNA amplification (PCR-SSOP) of 100 breast cancer Mexican mestizo patients and 99 matched healthy controls. HLA-A frequencies that we were able to observe that there was no difference between both groups from the statistical viewpoint. HLA-B*1501 was found three times more common in the case group (OR, 3.714; p = 0.031). HLA-Cw is not a marker neither for risk, nor protection for the disease, because we did not find significant statistical differences between the two groups. DRB1*1301, which is expressed in seven cases and in only one control, observing an risk increase of up to seven times and DRB1*1602, which behaves similarly in being present solely in the cases (OR, 16.701; 95% CI, 0.947 - 294.670). DQ*0301-allele expression, which is much more common in the control group and could be protective for the presentation of the disease (OR, 0.078; 95% CI, 0.027-0.223, p = 0.00001). Our results reveal the role of the MHC genes in the pathophysiology of breast cancer, suggesting that in the development of breast cancer exists a disorder of immune regulation. The triggering factor seems to be restricted to certain ethnic groups and certain geographical regions since the relevant MHC alleles are highly diverse. This is the first study in Mexican population where high resolutions HLA

    A polygenic model has been proposed in order to explain the genetic susceptibility to sporadic breast cancer. According to this model, common population variants would be responsible for low to modest effects on the risk of developing the disease. We have carried out a high-throughput SNP genotyping project in order to shed some light on the complex genetic aetiology of non-familial breast cancer. Ninety-one genes have been selected because of their implications in several candidate cell pathways for breast cancer. A total of 640 SNPs in these genes were genotyped in a series of 450 consecutive cases and 448 controls from mainland Spain. Promising SNPs were then studied in an independent series of 294 cases and 299 controls from the Canary Islands. In the first case-control series we identified 25 SNPs with P-values below 0.05 (under a 1 df Chi-square test), five of them with P-values below 0.01 (best=0.0008). In the stage 2 Canary Islands series, odd ratios (OR) for two SNPs in HUS1 were in a consistent direction. SNPs located at the gene HUS1 are good candidates for further investigation in independent association studies and functional assays.

    The objective of our study was to assess ergonomic and diagnostic performance-related issues associated with the interpretation of digital breast tomosynthesis-generated examinations. Thirty selected cases were read under three different display conditions by nine experienced radiologists in a fully crossed, mode-balanced observer performance study. The reading modes included full-field digital mammography (FFDM) alone, the 11 low-dose projections acquired for the reconstruction of tomosynthesis images, and the reconstructed digital breast tomosynthesis examination. Observers rated cases under the free-response receiver operating characteristic, as well as a screening paradigm, and provided subjective assessments of the relative diagnostic value of the two digital breast tomosynthesis-based image sets as compared with FFDM. The time to review and diagnose each case was also evaluated. Observer performance measures were not statistically significant (p > 0.05) primarily because of the small sample size in this pilot study, suggesting that showing significant improvements in diagnosis, if any, will require a larger study. Several radiologists did perceive the digital breast tomosynthesis image set and the projection series to be better than FFDM (p < 0.05) for diagnosing this specific case set. The time to review, interpret, and rate the examinations was significantly different for the techniques in question (p < 0.05). Tomosynthesis-based breast imaging may have great potential, but much work is needed before its optimal role in the clinical environment is known.

    The histological grade/stage of tumor is widely acknowledged as an important clinical prognostic factor for cancer progression. Recent experimental studies have explored the following two topics at the molecular level: (1) whether or not gene expression levels vary by different degrees among different tumor grades/stages, and (2) whether some well-defined modules could distinguish one grade/stage from another. In this article, using breast cancer as an example, we investigated this topic and ...

    Knowledge on proper nutrition favours the creation of pro-healthy nutritional behaviours of people. Studies related to the nutritional knowledge of adults, diet quality and incidence of breast or lung cancers are limited. Analysis of the relationship between the level of nutritional knowledge, diet quality and risk of breast cancer in women or lung cancer in men from the Warmia and Mazury region in Poland. The study was carried out in 202 subjects aged 23-80 years, including 107 women (17 cases of breast cancer) and 95 men (54 cases of lung cancer) from the Warmia and Mazury region in Poland. Nutritional knowledge was evaluated with the Questionnaire of Eating Behaviours (QEB), including 25 statements. Based on the frequency of the consumption of 16 food items, two diet quality indices were created: the pro-Healthy-Diet-Index-8 (pHDI-8) and the non-Healthy-Diet-Index-8 (nHDI-8). The values of pHDI-8 and nHDI-8 were calculated on the basis of the sum of the daily frequency of consumption of the selected food items and expressed as times/day. The Odds Ratio (OR) of both breast cancer or lung cancer in relation to the level of nutritional knowledge was calculated based on a logistic regression analysis. The incidence of breast or lung cancer in the bottom, middle and upper tertile of nutritional knowledge was 57.6%, 32.6% and 15.8%, respectively. As nutritional knowledge grew in the subsequent tertiles, pHDI-8 was on the increase (2.63 vs. 3.78 vs. 4.22 times/day) and n-HDI-8 was on the decrease (1.32 vs. 1.21 vs. 0.94 times/day). In the upper tertile of nutritional knowledge, the Odds Ratio for the incidence of breast or lung cancers varied from 0.06 (95% CI: 0.02; 0.17; pcancer type and age) to 0.17 (95% CI: 0.04; 0.69; pcancers varied from 0.27 (95% CI: 0.12; 0.62, pcancer type and age) to 0.35 (95% CI: 0.18; 0.71, pdiet and lower risk of breast cancer in women or lung cancer in men. In contrast, a lower level of nutritional knowledge was associated with a lower

    Role of hair dyes in the etiology of breast cancer has occasionally raised concern but previous research has concluded with mixed results. Remnants of prohibited aromatic amines have been found in many hair dye products, and elevated levels of DNA-adducts of these amines have been detected from breast epithelial cells of hair dye users. However, the IARC working group has concluded that there is inadequate evidence for carcinogenicity of personal hair dye use and limited evidence in experimental animals for carcinogenicity of hair colorants. We investigated whether the use of hair dyes is associated with breast cancer risk in women. The study design was a retrospective population-based case-control study in Finland, with a self-administered questionnaire from 6,567 breast cancer patients, aged 22-60 years and diagnosed in 2000-2007, and their 21,598 matched controls. We report odds ratios (OR) with 95% confidence interval (95% CI) from a conditional logistic regression model applied to the frequency matched sets of cases and controls. Bias-adjusted odds ratios from the sensitivity analysis are also presented. After adjusting for potential confounders, the odds of breast cancer increased by 23% (OR: 1.23, 95% CI: 1.11-1.36) among women who used hair dyes compared to those who did not. In women born before 1950 an increase of 28% was noted (OR: 1.28, 95% CI: 1.10-1.48). We also observed a significant trend between the OR and cumulative use of hair dyes (P: 0.005). Bias-adjusted odds ratios varied between 1.04 and 2.50. Our results suggest that use of hair dyes is associated with breast cancer incidence. The impact on public health may be substantial due to vast popularity of hair coloring in modern societies. It should be noted that regardless of all efforts, a possibility of bias cannot definitively be ruled out and use of a prospective design is warranted. Based on the present results, it may be concluded however that safety of hair dyes in relation to breast

    Full Text Available Diffuse dermal angiomatosis (DDA is a rare reactive angioproliferation in the skin and considered to be a subtype in the group of cutaneous reactive angiomatoses. DDA is clinically characterized by livedoid patches and plaques with tender ulceration. Its histologic features are a reactive diffuse proliferation of bland endothelial cells and pericytes within the dermis, forming small capillary vessels. Previously described cases of DDA most commonly involved the limbs and were associated with a wide spectrum of predisposing comorbidities, especially advanced atherosclerotic vascular disease and arteriovenous fistula. However, several cases of DDA of the breast (DDAB have been reported in recent years. In this study we present 2 additional patients with DDAB and review all 36 cases of DDAB published in the literature. We describe the clinical and histopathologic characteristics, hypothesized pathogenetic mechanisms, and predisposing conditions of this rare skin disorder and discuss treatment options. The breast is a more commonly involved site of DDA than previously believed. DDAB typically occurs in middle-aged women and is associated with macromastia, overweight or obesity, and probably smoking. Predisposing comorbid conditions differ from those of DDA involving other parts of the body, making DDAB a unique clinicopathologic entity in the spectrum of cutaneous reactive angiomatoses. Currently there is no consensus on the best therapeutic approach. Isotretinoin and other medical therapies have been used with limited success. Breast reduction surgery appears to be a viable treatment option for DDAB in women with macromastia and might provide definitive healing.

    Breast cancer is the most common cause of cancer death among women. Several studies have investigated the relationship between the C3435T polymorphism of ABCB1 gene and risk of breast cancer; but the results are conflicting. In the present study, we sought to assess the relationship between the C3435T polymorphism in ABCB1 gene and the risk of breast cancer in a sample of the Moroccan population. A case control study was performed on 60 breast cancer patients and 68 healthy women. The ABCB1 C3435T polymorphism was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. Furthermore, a meta-analysis including 16 studies with 6094 cases of breast cancer and 8646 controls was performed. Genotype frequencies were 50 % for CC, 33.3 % for CT and 16.7 % for TT in patients and 41.2 % for CC, 48.5 % for CT and 10.3 % for TT respectively in the control group. This difference was not statistically significant. The same trend as observed in the allele distribution between patients and controls (P = 0.84). Findings from the meta-analysis showed that the ABCB1 C3435T polymorphism was not associated with an increased risk of breast cancer in the dominant model (OR = 0.907; 95 % CI = 0.767-1.073; P = 0.25) as well as in the recessive model (OR = 1.181; 95 % CI = 0.973-1.434; P = 0.093) and in the allele contrast model (OR = 1.098; 95 % CI = 0.972-1.240; P = 0.133). However, the stratification of studies on ethnic basis showed that the TT genotype was associated with the risk of breast cancer in Asians (OR = 1.405; 95 % CI = 1.145-1.725; P = 0.001), Caucasians (OR = 1.093; 95 % CI = 1.001-1.194; P = 0.048) and North African (OR = 2.028; 95 % CI = 1.220-3.371; P = 0.006). We have noted that the implication of C3435T variant on the risk of breast cancer was ethnicity-dependent. However, there is no evidence that ABCB1 C3435T polymorphism could play a role in

    Pregnancy-associated breast cancer (PABC) constitutes 7% of all BCs in young women. The prognosis of PABC remains controversial. In this study, we evaluated the impact of the association of pregnancy with BC on the rates of overall survival (OS), disease free survival (DFS), and distant and local recurrence-free survival. We conducted a retrospective unicenter case-control study. We enrolled PABC patients treated at our institution between 1992 and 2009. For each case, 2 BC controls were matched for age and year of diagnosis. Univariate and multivariate analyses were performed to assess the parameters associated with prognosis. Eighty-seven PABC patients were enrolled and matched with 174 controls. The univariate analysis did not reveal any significant differences in OS, DFS or distant recurrence rates between the 2 groups. Pregnancy associated status, a tumor larger than T2 and neoadjuvant chemotherapy as the primary treatment were significantly associated with an increased risk of local relapse. The multivariate analysis showed that the pregnancy associated status and the tumor size were strong prognostic factors of local recurrence. Pregnancy associated status negates the prognostic value of tumor size, as both T0-T2 and T3-T4 PABC patients have the same poor prognosis as control BC patients with T3-T4 tumors. Interestingly, although PABC patients have more locally advanced tumors, they did not have a higher rate of radical surgery than the control BC patients. Pregnancy associated status is a strong prognostic factor of local relapse in BC. In PABC patients, when possible, radical surgery should be the preferred first treatment step.

    Full Text Available Purpose. To study the distribution of breast mammogram density in Lebanese women and correlate it with breast cancer (BC incidence. Methods. Data from 1,049 women who had screening or diagnostic mammography were retrospectively reviewed. Age, menopausal status, contraceptives or hormonal replacement therapy (HRT, parity, breastfeeding, history of BC, breast mammogram density, and final BI-RADS assessment were collected. Breast density was analyzed in each age category and compared according to factors that could influence breast density and BC incidence. Results. 120 (11.4% patients had BC personal history with radiation and/or chemotherapy; 66 patients were postmenopausal under HRT. Mean age was 52.58±11.90 years. 76.4% of the patients (30–39 years had dense breasts. Parity, age, and menopausal status were correlated to breast density whereas breastfeeding and personal/family history of BC and HRT were not. In multivariate analysis, it was shown that the risk of breast cancer significantly increases 3.3% with age (P=0.005, 2.5 times in case of menopause (P=0.004, and 1.4 times when breast density increases (P=0.014. Conclusion. Breast density distribution in Lebanon is similar to the western society. Similarly to other studies, it was shown that high breast density was statistically related to breast cancer, especially in older and menopausal women.

    The aim of this study was to analyze and compare foot health and general health in a sample of women divided into two groups: 1) those with breast cancer and undergoing chemotherapy treatment and 2) healthy women without breast cancer and with normalized reference values. A case-control observational study was performed. Two-hundred women with a mean age of 51.00±8.75 years were recruited from podiatric medicine and surgery clinics from the University of Extremadura (Plasencia, Spain) and the Hospital Infanta Cristina (Badajoz, Spain). The women were divided into case and control groups (undergoing chemotherapy treatment and healthy women, respectively). The Foot Health Status Questionnaire was used to assess foot health domain scores. Significant differences between both groups were seen for foot pain (P=0.003), foot function (Pquality of life. Clinical aspects with emphasis on foot pain and disability were increased. Furthermore, physical activity, social capacity, and vigor were affected. Therefore, general health care and foot problem prevention for breast cancer survivors should be given more consideration.

    Polyacrylamide hydrogel (PAAG), once used as an injection for breast augmentation, has been banned in the medical field for cosmetic purposes for more than 10 years in China. But a large number of breasts have characteristic deformities due to the gel's feature of erosion. Our aim is to explore a retrospective study on PAAG's long-term effects on women, ensuing breast deformity and the strategy for breast plasticity after removing the gel in our center from 2007 to 2014. From 2007 to 2014, 200 patients, whose breasts were injected with PAAG, underwent the operation to remove the injectable material. Complications were summarized. Ultrasound or MRI was performed before the operation to disclose the general distribution of the gel and the muscle and gland infiltration. According to the gel distribution, muscle and gland infiltration, infection, gel residue, and other factors, the patients were treated, respectively, with or without prosthesis implantation surgery after the removal of the gel. According to the decision about whether or when to undergo prosthesis implantation, the patients were classified into three types: group I-prosthesis implantation at the first stage, group II-prosthesis implantation at the second stage, and group III-only removing the material without prosthesis implantation. The scores of the BREAST-Q program were used to evaluate the preoperative and postoperative differences. Seventy-seven patients underwent prosthesis implantation at the first stage and 61 patients were operated on by placing the prosthesis at the second stage. A total of 62 patients only underwent the PAAG removal operation.

    Solvents contaminated drinking water supplies at Marine Corps Base Camp Lejeune during 1950s-1985. We conducted a case-control study among Marines to evaluate associations between residential exposure to contaminated drinking water at Camp Lejeune and male breast cancer risk. The study included 71 male breast cancer cases and 373 controls identified from the Department of Veteran's Affairs (VA) cancer registry whose military personnel records were available. Controls were selected from cancers not known to be associated with solvent exposure and included 270 skin cancers, 71 mesotheliomas, and 32 bone cancers. Base assignment and risk factor information came from military personnel and VA records. Groundwater contaminant fate/transport and distribution system models provided monthly estimated residential contaminant levels. We conducted exact logistic regression using the 50th percentile level among exposed controls to create low and high exposure categories. We calculated 95% confidence intervals (CIs) to indicate precision of effect estimates. Exploratory analyses used proportional hazards methods to evaluate associations between exposures and age at diagnosis. After adjusting for age at diagnosis, race, and service in Vietnam, the odds ratio (OR) for ever stationed at Camp Lejeune was 1.14 (95% CI: 0.65, 1.97). Adjusted ORs for high residential cumulative exposures to tetrachloroethylene (PCE), t-1,2 dichloroethylene (DCE), and vinyl chloride were 1.20 [95% CI: 0.16-5.89], 1.50 [95% CI: 0.30-6.11], 1.19 [95% CI: 0.16-5.89], respectively, with a monotonic exposure response relationship for PCE only. However these results were based on two or three cases in the high cumulative exposure categories. Ever stationed at Camp Lejeune and high cumulative exposures to trichloroethylene (TCE), PCE, DCE and vinyl chloride were associated with earlier age at onset for male breast cancer; hazard ratios ranged from 1.4-2.7 with wide confidence intervals for cumulative exposure

    Male breast cancer is rare, and experience of it in any single institution is limited. Our current understanding regarding its biology, natural history, and treatment strategies has been extrapolated from its female counterpart. The aim of this study is to evaluate the expression patterns of estrogen receptor (ER), progesterone receptor (PR), MiB1 (Ki67), Her-2/neu (c-erbB2), and p53 and to correlate them with the prognosis, presentation, staging, management, and survival/outcome in male breast carcinoma identified through the Veterans Administration nationwide cancer registry. Sixty-five cases of male breast cancer were reviewed for classification. Tumor blocks were requested from each institution for immunohistochemical staining and evaluation of ER, PR, p53, Her2-neu, and MiB1. Seventeen age- and disease-matched male veteran patients with breast gynecomastia were used as controls. Traditional prognostic data were collected for comparison with female breast cancers (i.e., age, lymph node status, clinical staging, tumor size, histological grade, and disease-free and overall survival). Male breast carcinoma had worse disease-free survival than controls (P =.03). The clinical stage regardless of tumor size or lymph node metastasis was the single most significant prognostic factor (P <.0001). ER-positive patients appeared to have a better survival than did ER-negative patients (P =.03, univariate; P not significant in multivariate) and did not benefit from treatment with tamoxifen (P =.0027, univariate; P =.42, multivariate). MiB1 and PR expressions did not correlate with treatment or survival, and p53 was associated with shorter disease free survival (P =.07, univariate; P =.047, multivariate). Stage for stage, Her2-neu was associated with shorter disease-free survival (P <.0001) and correlated with positive lymph nodes (P =.08). Surgery alone versus surgery with adjuvant treatments (chemotherapy, radiotherapy, tamoxifen, or combination) did not show any survival

    Fibroadenomatoid hyperplasia of the breast (FAHB) is a rare benign breast lesion and its clinical features are similar to fibroadenoma and fibrocystic changes. FAHB has been previously termed sclerosing lobular hyperplasia, fibroadenomatosis, fibroadenomatoid change, or fibroadenomatoid mastopathy. Typically, FAHB is derived from stroma and epithelia. The pathologic characteristics of FAHB are microfocal lobulocentric proliferation of stroma accompanied by epithelial and myoepithelial components resembling similar histological changes, as found in fibroadenoma, apocrine hyperplasia, intraductal hyperplasia, and lobular hyperplasia. FAHB could be present as a localized or diffused pattern in pathology. Most cases show no well-circumscribed mass lesions and no apparent capsules; it is usually identified as an incidental finding in other benign lesions or in random sampling in cancerous breast tissues. FAHB is categorized as a benign proliferative breast disease and it has previously been reported; however, the authors believe this study may be the first case with two giant masses reported. Fiber adenoma hyperplasia is a rare cystic hyperplasia of breast pathology and its ultrasonographic manifestations are easily confused with breast cancer. Comparative MRI ultrasound analysis will help make the differential diagnosis. © 2014 S. Karger AG, Basel.

  10. A Molecular Case-Control Study on the Association of Melatonin Hormone and rs#10830963 Single Nucleotide Polymorphism in its Receptor MTNR1B Gene with Breast Cancer

    Full Text Available Background: The main function of the pineal hormone melatonin which is mediated via its two receptors, MTNR1A and MTNR1B, is to mediate dark signals in addition to anti-oxidation, immune system enhancement, protection from radiation, and anti-cancer functions. A common single nucleotide polymorphism in the MTNR1B gene is rs#10830963, which is well known as a risk factor for type 2 diabetes mellitus. This study intends to figure out the role of melatonin and its receptor MTNR1B gene rs#10830963 polymorphism in breast cancer incidence, diagnosis and prognosis. Methods: This study included 43 females with breast cancer and 45 apparently normal healthy females. Restriction fragment length polymorphism-PCR was used for amplification and genotyping of the MTNR1B gene rs#10830963 polymorphism in whole blood. Serum melatonin levels were measured using a ready-for-use radioimmunoassay kit. Results: For the MTNR1B gene rs#10830963 polymorphism, we observed a significantly higher GG genotype frequency among cases (72.1% than controls (13.3%, with a diagnostic sensitivity of 83.78% and specificity of 76.47%. The cases had a frequency of 11.6% for the CC genotype and 16.3% for the CG genotype which was significantly lower compared to controls that had a 44.4% frequency of the CC genotype and 42.2% frequency of the CG genotype. The GG genotype had a significant association with larger tumor volume (P=0.048. Serum melatonin levels were significantly lower among breast cancer patients than controls. Using the ROC curve analysis, serum melatonin showed a significant AUC (72.6%, P39.5 pg/ml. Conclusion: The risk for breast cancer incidence increased as the serum levels of melatonin decreased and in females homozygous for the G allele (GG genotype of the MTNR1B gene rs#10830963 polymorphism. The GG genotype was found to be associated with increased breast tumor volume as a marker of a poor prognosis breast cancer.

    Full Text Available Background and Objectives: There are inconsistent results about the association between ischemic cerebrovascular disease and tamoxifen use in women with breast cancer. The study aimed to evaluate the association between the risk of ischemic cerebrovascular disease and tamoxifen use in older women with breast cancer in Taiwan.Methods: We designed a retrospective, nationwide, case-control study using the database of the Taiwan National Health Insurance Program. A total of 800 female subjects with breast cancer aged ≥65 years with the first episode of ischemic cerebrovascular disease from 2000 to 2011 were identified as the cases. Additionally, 2,876 female subjects with breast cancer aged ≥65 years without any type of cerebrovascular diseases were selected as the control subjects. The cases and the control subjects were matched with age and comorbidities. Ever use of tamoxifen was defined as a subject who had at least a prescription for tamoxifen before the index date. Never use of tamoxifen was defined as a subject who never had a prescription for tamoxifen before the index date. We used the multivariable logistic regression model to calculate the odds ratio (OR and 95% confidence interval (CI for ischemic cerebrovascular disease associated with tamoxifen use.Results: After adjusting for confounding variables, the adjusted OR of ischemic cerebrovascular disease was 2.5 for subjects with ever use of tamoxifen (95% CI 2.10, 2.97, compared with never use of tamoxifen. In addition, the adjusted OR of ischemic cerebrovascular disease was 1.15 (95% CI 1.10, 1.21 in subjects with ever use of tamoxifen as increase in use duration per 1 year. The adjusted OR of ischemic cerebrovascular disease was 2.54 (95% CI 2.03, 3.17 in subjects with ever use of tamoxifen as increase in dosage per 1 mg.Conclusions: Tamoxifen use is significantly associated with 2.5-fold increased odds of ischemic cerebrovascular disease among older women with breast cancer in

    Full Text Available Background: Metastatic tumors in the breast require treatment according to origin and type of tumor. It is important to recognize these lesions in fine-needle aspiration cytology (FNAC in order to avoid unnecessary mastectomy or non-relevant chemotherapy. The aim of this study was to evaluate the cytological features of metastatic tumors and possible criteria that could alert us as to the possibility of a metastasis from an extra mammary malignancy. Methods: The material included 36 confirmed or suspected metastases in the breast registered in the pathology files at Oslo University Hospital, Ulleval, during 1990-2007. There were a total of 6,325 cases of malignant breast FNAC, representing 30 men and 6,295 women. Smears were evaluated for the amount of material, presence or absence of myoepithelial cells, microcalcifications, mitoses and necrotic material. All carcinomas were graded. Results: There were seven men (7/30 = 23.3% and 29 women (29/6,295 = 0.46%. The primary tumor was known in 22 cases (22/36 = 61.1%. No other primary tumor was known and metastatic lesion was not initially suspected in 14 cases (14/36 = 38.9%. The most common origin was lung (15/36 = 41.7%. In five cases (5/36 = 13.9%, the origin remained uncertain. Conclusions: Metastases from extra mammary sites are (relatively common in males (23.3%. In women, metastatic lesions are rare (0.46%. A large proportion of them (88% are high-grade adenocarcinomas and poorly differentiated carcinomas that may resemble grade 3 ductal carcinomas. Unusual clinical and/or radiological presentation in combination with high-grade malignant cells should alert us to consider the possibility of a metastasis.

    Tuberous breasts are widely known and described. Several surgical strategies have been proposed; however, few studies explain the origin or structural alterations of this deformity. No histological studies have been performed. The present article describes a morphological and histological study of breast tissue specimens. Mammary specimens of 22 female and five male patients with tuberous breasts were histologically analyzed and compared with six specimens harvested from normal female breasts and from three cases of true 'normal' gynecomastia. A high prevalence of one histological subtype was observed, with the presence of collagen fibres among few fibroblasts. Histochemical analysis highlighted alterations of the arrangement and of the quantity of collagen involving breast structures. Results of the present study suggest that collagen deposition alterations can better explain breast parenchyma modifications. Histological features of male subjects support this theory. Additionally, the observation of two cases in male homozygous twins suggests the role of genetic influences.

  18. KRAS rs61764370 is associated with HER2-overexpressed and poorly-differentiated breast cancer in hormone replacement therapy users: a case control study

    Full Text Available Abstract Background A single nucleotide polymorphism located in the 3'-untranslated region of the KRAS oncogene (KRAS variant; rs61764370 disrupts a let-7 miRNA binding and was recently reported to act as a genetic marker for increased risk of developing human cancers. We aimed to investigate an association of the KRAS variant with sporadic and familial breast cancer and breast tumor characteristics. Methods Genotyping was accomplished in 530 sporadic postmenopausal breast cancer cases, 165 familial breast cancer cases (including N = 29, who test positive for BRCA1/2 mutations and 270 postmenopausal control women using the flurogenic 5' nuclease assay. Information on hormone replacement therapy (HRT use and tumor characteristics in sporadic breast cancer cases was ascertained from a postal questionnaire and pathology reports, respectively. Associations between the KRAS genotype and breast cancer or breast tumor characteristics were assessed using chi-square test and logistic regression models. Results No evidence of association was observed between the KRAS variant and risk of sporadic and familial breast cancer - either among BRCA carriers or non-BRCA carriers. The KRAS variant was statistically significantly more often associated with human epidermal growth factor receptor 2 (HER2 - positive tumors and tumors of higher histopathologic grade. However, both associations were detected only in HRT users. Conclusion Our data do not support the hypothesis that the KRAS variant rs61764370 is implicated in the aetiology of sporadic or of familial breast cancer. In postmenopausal women using HRT, the KRAS variant might lead to HER2 overexpressed and poorly-differentiated breast tumors, both indicators of a worse prognosis.

    2016-03-01

    Full Text Available Background: Gestational or pregnancy-associated breast cancer is defined as breast cancer diagnosed during pregnancy, within the first postpartum year, or during lactation. Breast cancer is one of the most common cancers in nonpregnant and pregnant women. Case presentation: A 29-year-old pregnant woman presented at eight weeks gestational age with a palpable breast nodule. On breast ultrasound evaluation, only probably benign findings were detected. The pregnancy was uneventful until the third trimester when she started to have a severe back pain which became gradually resistant to medical therapy. Therefore, at 33 weeks, she was assisted at an emergency care facility and a highly suspicious breast mass was detected. A core biopsy was performed that revealed an invasive ductal carcinoma grade 3 with lymph node metastasis. After several imaging studies, it was diagnosed as a stage 4 breast cancer with bone, liver, and pulmonary metastasis. At thirty four weeks gestation, the pregnancy was terminated by C-section and she started to receive palliative radiation therapy one week later. She also received several cycles of palliative chemotherapy. Nineteenth months after C-section, progression of the disease was observed and a cerebellar metastasis was found. Unfortunately, two months later, her clinical condition deteriorated and the patient died.Conclusion: Gestational breast cancer represents a clinical situation of utmost important in which the health of both the mother and the fetus should be taken into account. Diagnosis is difficult due to the physiological changes of the mammary glands during pregnancy and lactation, and it usually occurs at an advanced stage.

    2013-06-01

    The thyroid gland is an uncommon site for metastasis to develop and thus metastases arising from breast cancer are rarely observed. In the present study, we describe a case of a 45-year-old female with a three-year history of breast cancer who presented with a thyroid mass that was diagnosed as metastatic breast carcinoma by histopathological analysis of the subtotal thyroidectomy specimen. To ascertain the diagnosis of metastatic breast cancer, we evaluated two types of markers; those that possessed a similar expression status in the original and metastatic lesions [ER, PR and CerbB-2 (HER2/neu)], and those that are capable of differentiating between metastatic lesions and the surrounding thyroid components (TG and TTF-1). The results showed that ER, PR and CerbB-2 demonstrated a similar expression pattern in primary breast carcinoma and thyroid lesions. Meanwhile, in the thyroid lesions, the malignant cells showed negative staining for TG and TTF-1, which confirmed that lesions were not thyroid in origin. This case may prompt clinicians that although thyroid gland are uncommon metastatic site, a diagnosis of metastatic disease should be considered when new aggregates are identified in the thyroid glands and histopathological analysis may aid the diagnosis.

    Full-field digital mammography, which is gradually being introduced in most clinical and screening settings, produces two types of images: raw and processed. However, the extent to which mammographic density measurements, and their ability to predict breast cancer risk, vary according to type of image is not fully known. We compared the performance of the semi-automated Cumulus method on digital raw, "analogue-like" raw and processed images, and the performance of a recently developed method - Laboratory for Breast Radiodensity Assessment (LIBRA) - on digital raw and processed images, in a case-control study (414 patients (cases) and 684 controls) by evaluating the extent to which their measurements were associated with breast cancer risk factors, and by comparing their ability to predict breast cancer risk. Valid Cumulus and LIBRA measurements were obtained from all available images, but the resulting distributions differed according to the method and type of image used. Both Cumulus and LIBRA percent density were inversely associated with age, body mass index (BMI), parity and postmenopausal status, regardless of type of image used. Cumulus percent density was strongly associated with breast cancer risk, but with the magnitude of the association slightly stronger for processed (risk increase per one SD increase in percent density (95 % CI): 1.55 (1.29, 1.85)) and "analogue-like" raw (1.52 (1.28, 1.80)) than for raw (1.35 (1.14, 1.60)) images. LIBRA percent density produced weaker associations with risk, albeit stronger for processed (1.32 (1.08, 1.61)) than raw images (1.17 (0.99, 1.37)). The percent density values yielded by the various density assessment/type of image combinations had similar ability to discriminate between patients and controls (area under the receiving operating curve values for percent density, age, BMI, parity and menopausal status combined ranged from 0.61 and 0.64). The findings showed that Cumulus can be used to measure density on all

    To summarize the experience of diagnosis and treatment of occult breast cancer in 44 cases. Clinicopathological data of 44 cases of occult breast cancer initially presenting axillary mass alone treated in our department during Jan 1997 to Dec 2008 were retrospectively analyzed. The 44 patients with occult breast cancer accounted for 0.42% of all breast cancer patients admitted to our hospital and institute in the same period. The surgery included radical mastectomy in 16 cases, modified radical mastectomy in 19 cases, axillary clearance in 1 case, and simple axillary node excision in 8 cases. Follow-up, ranging from 12-132 months, was available in 38 cases. Among 32 cases who underwent mastectomy or axillary clearance, 2 cases died of distant metastases and 3 cases were still alive with local recurrence at the time of analysis. In two out of six cases who refused further surgical treatment received mastectomy 16 months and 41 months after the primary diagnosis of occult breast cancer, respectively. Others were alive without evidence of recurrence or metastases at the time of analysis. Occult breast cancer should be taken into consideration in cases presenting with axillary metastasis of unknown primary origin. The treatment of occult breast cancer should include modified radical mastectomy/radical mastectomy or breast conserving surgery combined with breast irradiation.

    Previous studies suggest a possible association between ABO blood group and the risk of breast cancer. The aim of this study is to investigate the presence of a possible association between breast cancer and blood groups ABO and Rh. 549 women including 173 cases and 376 controls were selected. The case group included patients with breast cancer and the cancer diagnosis was confirmed for all of them. The control group included women with no reports of breast cancer. Blood group sampling of all cases was performed. The obtained information regarding presence or absence of cancer, blood type, age group and type of cancer were analyzed. There is no significant association between blood types ABO (Rh) and the breast cancer. (P > 0.05) It has been found that the prevalence of invasive intraductal carcinoma was 85% among the cases. About 5% of the total diagnosed cancers in the case group were allocated to modularly carcinoma, invasive lobular carcinoma and Paget's disease. There was no relative frequency in specific blood group for these three types of cancer. The blood types ABO (Rh) and breast cancer type showed no significant relation (P = 0.2). According to the obtained results from this study, there was no relative frequency in specific blood group for these three types of cancer and the blood type could not be influenced as a risk factor in breast cancer.

    The invasive lobular carcinoma of the breast, the incidence of which is 10-15%, occupies a special position in respect of histological differentiation and biological behaviour. No MR signal enhancement was seen after contrast medium application in the tumoral tissue in the case described here, namely, an invasive lobular carcinoma of the breast of 2 cm size. Hence, it is not always possible to exclude with absolute certainty the presence especially of an invasive lobular carcinoma of the breast in the absence of contrast medium uptake. (orig.)

  9. A Case of Conjunctival Melanoma Presenting with Breast Metastasis

    Full Text Available Most breast masses arise from the breast. Metastasis to the breast is fairly uncommon, but can occur in breast skin and parenchyma. In particular, leukemia and lung cancers, and MM may metastasize to the breast. Breast metastasis might be the first symptom or may occur during the course of other malignancies. Our case presented with a fixed mass in the upper-medial quadrant of her left breast during regular follow-up visits. The mean time to breast metastasis in patients with MM is 62 months (13-178. In our case this time was 48 months. In a case series with 7 patients hematological malignancies (Hodgkin lymphoma, non-Hodgkin lymphoma, and leukemia were the leading cause of breast metastasis, whereas in only 1 case the cause was MM. In another case series of 15 MM patients with metastasis to the breast, the primary tumor was frequently localized to the upper extremities and trunk. In a report of 250 conjunctival MM cases the mortality rate was significantly higher in patients with tumors >4 mm in vertical thickness. In another 45-case MM series tumors with a diameter >10 mm were associated with higher mortality rates. In our case the thickness of the tumor was 5 mm. In conclusion, histopathological evaluation should be mandatory in patients with known primary malignancies in order to differentiate new primary tumors, metastases, and benign tumors.

    Scientific certainty regarding environmental toxin-related etiologies of breast cancer, particularly among women with genetic polymorphisms in estrogen metabolizing enzymes, is lacking. Fungicides have been recognized for their carcinogenic potential, yet there is a paucity of epidemiological studies examining the health risks of these agents. The association between agricultural fungicide exposure and breast cancer risk was examined in a secondary analysis of a province-wide breast cancer case-control study in Prince Edward Island (PEI) Canada. Specific objectives were: (1) to derive and examine the level of association between estimated fungicide exposures, and breast cancer risk among women in PEI; and (2) to assess the potential for gene-environment interactions between fungicide exposure and a CYP1A1 polymorphism in cases versus controls. After 1:3 matching of 207 cases to 621 controls by age, family history of breast cancer and menopausal status, fungicide exposure was not significantly associated with an increased risk of breast cancer (OR = 0.74; 95% CI: 0.46-1.17). Moreover, no statistically significant interactions between fungicide exposure and CYP1A1*2A were observed. Gene-environment interactions were identified. Though interpretations of findings are challenged by uncertainty of exposure assignment and small sample sizes, this study does provide grounds for further research.

    Each year, nearly 21,000 adolescents and young adults (AYA) ages 15 to 29 years are diagnosed with cancer. Breast and gynecological cancers account for 25% of the cancers seen in AYA females. The purpose of this study was to compare the current physical and mental health status of female AYA cancer survivors with non-cancer female controls. Using data from the population-based 2009 National Health Interview Survey, 100 cases of female AYA survivors of breast and gynecological cancers were identified [female AYA cancer survivor (FCS) group]. FCS cases were matched with 300 female respondents without a history of cancer on age, education, marital status, and minority status [non-cancer control (NCC) group]. The FCS and NCC groups were compared on a range of physical and mental health status indices using analysis of covariance and binary logistic regression. FCS group reported significantly poorer physical and mental health status than the matched controls. Relative to the NCC group, FCS survivors had significantly poorer scores on 7 of 8 mental health outcomes and were more likely to meet criteria for serious psychological distress (odds ratio = 4.23, p ≤ 0.001). FCS group also reported greater lifetime and current prevalence of various medical conditions, more health-related disabilities, and greater functional limitations than the NCC group. Diagnosis of breast and gynecological cancer during adolescence and young adulthood is associated with clinically important deficits in physical and mental health status. Given the young age of this cancer survivor cohort, increased attention should be devoted to minimizing these deficits.

    Breast cancer is one of the commonest cancers diagnosed among women around the world. Simulation approach has been utilized to study, characterize and improvise detection methods for breast cancer. However, minimal simulation work has been done to evaluate the surface stress of the breast with lumps. Thus, in this work, simulation analysis was utilized to evaluate and assess the breast surface stress due to the presence of a lump within the internal structure of the breast. The simulation was conducted using the Elmer software. Simulation results have confirmed that the presence of a lump within the breast causes stress on the skin surface of the breast.

    Full Text Available Matrix-producing breast cancer (MPC is a subtype of metaplastic carcinoma of the breast. It is a very rare tumor, which constitutes less than 1% of all malignant mammary tumors. The origin of this tumor is still unclear: there are molecular studies that suggest an origin from myoepithelial cells, whereas other studies underline the neoplastic transformation of a multipotent stem cell. Even the differential diagnosis of MPC and other breast neoplasms (phyllodes tumors and real sarcomas of the breast is not always easy. In the literature, a certain chemoresistance has been demonstrated, and a standard treatment of this tumor does not exist at this time. We report the case of a 44-year-old, premenopausal, female patient with a 6-cm breast lump. Neither imaging nor fine needle aspiration biopsy was crucial in achieving a diagnosis. The patient underwent a simple mastectomy. In consideration of the negative lymph node status, the patient was not subjected to radiotherapy or adjuvant chemotherapy. Moreover, since the receptor status was negative, hormone therapy was not necessary. The patient has been disease free for 4 years now.

    The purpose of this study was to determine the impact of revised ASCO/CAP 2013 HER2 guidelines on the clinical practice of pathologists and oncologists. Retrospective analysis of 1739 patients with invasive breast carcinoma who underwent reflex HER2 (fluorescence in situ hybridization [FISH]) testing, using both 2007 and 2013 guidelines (2007-2014). Using 2013 guidelines, 255 (15%; 95% confidence interval [CI], 13%-16%) cases were classified as HER2 + as opposed to 186 (11%; 95% CI, 9%-12%) by 2007 guidelines (odds ratio [OR] 1.4; 95% CI, 1.2-1.8; P = .0005). Sixty-nine cases equivocal by 2007 guidelines (12% of all equivocal cases) were converted to HER2 + by 2013 guidelines. Sixty-two of these 69 cases shifted from HER2 equivocal to positive due to change in FISH ratio cutoff from 2.2 to 2.0. Six cases had FISH ratio HER2 FISH equivocal cases was observed. Reflex FISH testing of all IHC 1+ cases at our institution additionally detected 58 patients (5%; 95% CI, 4%-6%) with HER2 amplification. The 2013 guidelines increase the detection of HER2 + cases, without introducing significant difference in discordance rate of the IHC and FISH assays. Inclusion of HER2 copy number criterion does not increase the number of FISH equivocal cases in our cohort. We recommend IHC 1+ cases should be offered reflex FISH testing because failure to test them will miss a small number (5%) of potentially treatable cases. Copyright © 2017 Elsevier Inc.

    Numerous clinical studies have suggested that chemopreventive drugs for breast cancer such as tamoxifen and exemestane can effectively reduce the incidence of estrogen receptor (ER)-positive breast cancer. However, it remains unclear how to identify those who are susceptible to ER-positive breast cancer. Accordingly, there is a great demand for a probe into the predisposing factors so as to provide precise chemoprevention. Recent evidence has indicated that ERα expression can be regulated by microRNAs (miRNAs), such as miR-206, in breast cancer. We assumed that single-nucleotide polymorphisms (SNPs) in the miR-206-binding sites of the target genes may be associated with breast cancer susceptibility with different ER statuses. We genotyped the SNPs that reside in and around the miR-206-binding sites of two target genes - heparan sulfatase 1 (SULF1) and RPTOR-independent companion of mammalian target of rapamycin Complex 2 (RICTOR) - which were related to the progression or metastasis of breast cancer cells in 710 breast cancer patients and 294 controls by the matrix-assisted laser desorption ionization-time of flight mass spectrometry method. Modified odds ratios (ORs) with their 95% confidence intervals (CIs) were calculated by a multivariate logistic regression analysis to evaluate the potential association between the SNPs and breast cancer susceptibility. For rs3802278, which is located in the 3'-untranslated region (3'-UTR) of SULF1, the frequency of the AA genotype was less in breast cancer patients than that in the controls as compared to that of the GG + GA genotype not only for ER-positive breast cancer patients (adjusted OR =0.663, P=0.032) but also for hormone receptor-positive breast cancer patients (adjusted OR =0.610, P=0.018). Besides, the frequency of the AA genotype was less than that of the GG genotype between the ER-positive breast cancer patients and the controls (adjusted OR =0.791, P=0.038).

    Identify the current physical and mental health status and health behaviors of male breast cancer survivors. Using data from the national, population-based, 2009 Behavioral Risk Factor Surveillance System (BRFSS) survey, 66 cases of male breast cancer were identified (mean age = 66.2 years, mean time since diagnosis = 12.0 years). Male breast cancer cases were matched with 198 male BRFSS respondents with no history of cancer (control group) on age, education, and minority status. The male breast cancer and control groups were compared on physical and mental health status and health behaviors, using t-test and logistic regression analyses. The male breast cancer group reported poorer physical and mental health than controls. Male breast cancer survivors were significantly (p physical comorbidities (Effect Size = 0.45) and activity limitations (Odds Ratio = 3.17), poorer life satisfaction (Effect Size = 0.41) and general health (Effect Size = 0.40), and more days in the past month when mental health (Effect Size = 0.49), and physical health (Effect Size = 0.29) were not good. In contrast, the male breast cancer and control groups were similar with regard to current health behaviors, including tobacco and alcohol use, diet, exercise, and health care. The diagnosis and treatment of male breast cancer may be associated with clinically important and long-term deficits in physical and mental health status, deficits which may exceed those evidenced by long-term female breast cancer survivors.

    Full Text Available OBJECTIVES: Breast hamartoma is an uncommon breast tumor that accounts for approximately 4.8% of all benign breast masses. The pathogenesis is still poorly understood and breast hamartoma is not a well-known disorder, so its diagnosis is underestimated by clinicians and pathologists. This study was designed to present our experience with breast hamartoma, along with a literature review. METHOD: We reviewed the demographic data, pathologic analyses and imaging and results of patients diagnosed with breast hamartoma between December 2003 and September 2013. RESULTS: In total, 27 cases of breast hamartoma operated in the Ankara University Medicine Faculty's Department of General Surgery were included in the study. All patients were female and the mean age was 41.8±10.8 years. The mean tumor size was 3.9±2.7 cm. Breast ultrasound was performed on all patients before surgery. The most common additional lesion was epithelial hyperplasia (22.2%. Furthermore, lobular carcinoma in situ was identified in one case and invasive ductal carcinoma was observed in another case. Immunohistochemical staining revealed myoid hamartoma in one case (3.7%. CONCLUSION: Breast hamartomas are rare benign lesions that may be underdiagnosed because of the categorization of hamartomas as fibroadenomas by pathologists. Pathologic examinations can show variability from one case to another. Thus, the true incidence may be higher than the literature indicates.

    Most Her2 testing guidelines recommend that all cases scoring Her2 2+ by immunohistochemistry should be analyzed by fluorescent in situ hybridization (FISH) to determine HER2 status to confirm eligibility for Trastuzumab therapy in breast cancer. The aim of our study was to determine HER2 gene and chromosome 17 (CEN17) status in a series of 108 Her2 2+ consecutive cases and study the correlation between pathological characteristics of the tumors and HER2 amplification. Invasive breast cancers were tested by FISH using the Dako HER2 FISH pharmDx kit. The Her2 immunohistochemistry protocol was performed using the polyclonal AO485 antibody (Dako) diluted to 1:1500. HER2 and CEN17 status were correlated to tumor SBR grade, mitotic count, estrogen receptor, progesterone receptor status and percentage of Her2 immunohistochemistry-positive cells. Following Food and Drug Administration guidelines, ie, HER2/CEN17 ratio >or=2 and an HER2 copy number >4, amplified cases were observed in 36 (33%) and 49 (45%) cases, respectively, and following American Society of Clinical Oncology/College of American Pathologists guidelines, ie, HER2/CEN17 ratio >2.2 and an HER2 copy number >6, amplified cases represented 30 and 24% of the study population, respectively. Chromosome 17 polysomy (CEN17 >2.25) was observed in 39 (36%) tumors. Significant positive correlations were found between FISH HER2 amplified cases and Her2 immunostaining >60% (P=1.1.10(-5)), SBR grade 3 (P=0.0001), nuclear atypia (P=0.03) and mitotic count (P=0.008). By multivariate analysis, Her2 immunostaining >60% (Por=2, only one had a ratio cases, one-third demonstrated HER2 amplification, and one-third had chromosome 17 polysomy. Pathological factors, in particular SBR grade 3 and more than 60% Her2+ cells, were significantly correlated with HER2 amplification.

    Full Text Available INTRODUCTION Metaplastic carcinoma of the breast (MCB denotes a heterogeneous group of rare malignant tumour of the breast expressing epithelial and/or mesenchymal tissue within the same tumour. AIMS To evaluate the clinicopathological features of 11 cases of metaplastic breast carcinoma in surgically excised malignant breast tumours in 8 years from April 2008 to March 2016. MATERIALS AND METHODS Total 284 consecutive cases of malignant breast lumps were removed surgically during study period, out of which 11 cases were diagnosed to have metaplastic breast carcinoma and were studied for its clinical features, size, site, gross morphological features, histopathological diagnosis, ER, PR, HER2 status, lymph node status. OBSERVATIONS Out of total 11 cases, 4 cases showed epithelial (tumour expressing adenocarcinoma and squamous cell carcinoma or squamous cell carcinoma alone, 6 cases showed biphasic (tumour expressing carcinoma and sarcomatoid or spindle cell component and 1 case showed monophasic (tumour exclusively of sarcomatoid or spindle cell component. The mean age of the patient was 44 years, 8 cases were triple ER/PR/HER2 negative. Largest tumour size was 16 cm with mean size of 7 cm. Only 3 cases showed lymph node metastasis on histopathology. CONCLUSION In our study of metaplastic breast carcinoma, patients were found to be younger–mean age 44 years, as compared with other studies of metaplastic breast carcinomas. Clinically, they had bigger size of tumour–mean 7 cm, at presentation, aggressive course with low regional lymph node metastasis-27.3%. Most of these cases were triple negative (72.7% for ER, PR and HER2 on immunohistochemical study.

    To assess dosimetric parameters in a case study where bilateral accelerated partial breast irradiation (APBI) is delivered using a strut-adjusted volume implant (SAVI) device. A 59-year-old female received APBI in both breasts over 5 days, with fractions of 3.4 Gy twice daily. A Vac-lok system was used for immobilization, and a C-arm was used for daily imaging. We generated dose-volume histograms (DVHs) for the brachytherapy plans to derive several important biologic factors. We calculated the normal tissue complication probability (NTCP), equivalent uniform dose (EUD), and tumor control probability (TCP) using the Lyman-Kutcher-Burman model parameters {alpha} = 0.3 Gy{sup -1}, {alpha}/{beta} = 4 Gy, n = 0.1, and m = 0.3. In addition, we assessed the dose homogeneity index (DHI), overdose index, and dose nonuniformity ratio. D95 was >95% and V150 was <50 mL for both breasts. The DHIs were 0.469 and 0.512 for the left and right breasts, respectively. The EUDs (normalized to 3.4 Gy b.i.d.) were 33.53 and 29.10 Gy. The TCPs were estimated at 99.2% and 99.9%, whereas the NTCP values were 4.2% and 2.57%. In this clinical case, we were able to quantify the dosimetric parameters of an APBI treatment performed with a SAVI device.

    Night work has been associated with risk of breast cancer but this association needs to be confirmed. Because breast cancer is an etiologically heterogeneous disease, we explored the association of night work with breast cancer subtypes defined by tumor status (positive of negative) for estrogen-receptor (ER), progesterone-receptor (PR) and human epidermal growth factor-receptor 2 (HER2). Using the data from a case-control study in France including 975 cases and 1317 controls, we found that the odds ratios for ER+, PR+ or HER2+ breast cancers subtypes were significantly elevated, while no association with night shift work was observed for ER, PR or HER2-negative tumors. After stratification by menopausal status, the associations of night work with receptor-positive breast tumor subtypes were clearly seen in premenopausal women (odds ratios 2.04, 1.98 and 2.80, respectively) but did not appear in postmenopausal women. This study provides evidence that working at night may increase risk of ER, PR and HER2-positive subtypes of breast cancer particularly among premenopausal women.

    Accessory breast tissue is a rare finding in the general population with an incidence of 1-2%. Carcinomas of accessory breast tissue account for ∼0.3% of breast cancers, 5% of which are arising within a supernumerary breast. They are usually diagnosed at a later stage compared with breast cancer, due to their rarity and low clinical suspicion. We present the case of a 58 years old male who was admitted to our hospital for an umbilical hernia, surgical repair. During surgery a small skin biopsy was excised and sent for pathological examination as routine procedure. The histological report revealed the presence of a poorly differentiated carcinoma. Immunochemical analysis confirmed adenocarcinoma of breast origin. Carcinomas of accessory breast tissue are rare and therefore they are usually of advanced stage in time of diagnosis. Few cases have been reported in literature of accessory breast tissue carcinomas in men. To the best of our knowledge, this is the only case in the literature, of ectopic breast tissue cancer in the umbilicus. Ectopic breast, Male breast cancer, Umbilicus.

    Enhancer of zeste homolog 2 (EZH2) is a polycomb-group protein that is involved in stem cell renewal and carcinogenesis. In breast cancer, increased EZH2 expression is associated with aggressiveness and has been suggested to identify normal breast epithelium at increased risk of breast cancer development. However, the association between EZH2 expression in benign breast tissue and breast cancer risk has not previously been evaluated in a large prospective cohort. We examined the association between EZH2 protein expression and subsequent breast cancer risk using logistic regression in a nested case-control study of benign breast disease (BBD) and breast cancer within the Nurses' Health Studies. EZH2 immunohistochemical expression in normal breast epithelium and stroma was evaluated by computational image analysis and its association with breast cancer risk was analyzed after adjusting for matching factors between cases and controls, the concomitant BBD diagnosis, and the Ki67 proliferation index. Women with a breast biopsy in which more than 20% of normal epithelial cells expressed EZH2 had a significantly increased risk of developing breast cancer (odds ratio (OR) 2.95, 95% confidence interval (CI) 1.11-7.84) compared to women with less than 10% EZH2 epithelial expression. The risk of developing breast cancer increased for each 5% increase in EZH2 expression (OR 1.22, 95% CI 1.02-1.46, p value 0.026). Additionally, women with high EZH2 expression and low estrogen receptor (ER) expression had a 4-fold higher risk of breast cancer compared to women with low EZH2 and low ER expression (OR 4.02, 95% CI 1.29-12.59). These results provide further evidence that EZH2 expression in the normal breast epithelium is independently associated with breast cancer risk and might be used to assist in risk stratification for women with benign breast biopsies.

    "Be Clear on Cancer" (BCOC) was a national campaign to raise awareness of breast cancer in women over seventy years old. Cancer Research UK conducted this campaign from 03 February 2014 to 15 March 2014. This study assesses its impact on breast care services. BCOC campaign guidelines for hospital trusts were used as standard comparator for this retrospective case-control study. All new patients referred to breast clinic over four months from February 2014 were included, and compared to the same period in 2013. Information was recorded for referrals, biopsy rates and pathological diagnoses. Intra & inter-group comparisons were performed. 1646 patients were included. An increase of 25.2%(n = 184) was observed in referrals in 2014(n = 915) compared to 2013(n = 731). Cancer detection rates went down significantly (P = 0.002,Chi-square) in 2014 (5.1%,n = 47) compared to 2013 (9.0%,n = 66) due to the increase in number of referrals. In the over 70s group, a higher than predicted increase of 64.2%(n = 52) in all referrals, and 8%(n = 44) in two-week wait referrals was observed. The number of biopsies and cancers detected remained stable although the proportions undergoing biopsies (2014-29.3%,n = 39/133 versus 2013-38.3%,n = 31/81) or being diagnosed with cancer (2014-19.5%,n = 26/133 versus 2013-30.9%,n = 25/81) declined significantly (P = 0.001,McNemar) during the campaign due to an inflation in the number of referrals. Despite the overall reduction, cancer detection rate for biopsies performed remained significantly high in the over 70s (66.7%,n = 26/39) when compared with the under 70s (23.9%,n = 21/88) during the campaign. Although "Be Clear on Cancer" campaign resulted in a significant increase in breast cancer referrals, it did not translate into an increase in biopsy rates or cancer detection rates. The amount of work generated for the hospital because of this campaign was far greater than the predicted increase from campaign pilots

    Cholesterol granuloma is histologically characterized as fibrous granulation tissue containing cholesterol crystals within surrounding giant cells. Cases of cholesterol granuloma of the breast are rare. In fact, only eight cases have been previously described, and of these, an ultrasonography was performed in only. Here, we report the ultrasonographic findings of a breast cholesterol granuloma accompanied with a literature review.

    Full Text Available Abstract Introduction Mycobacterium fortuitum is a rapidly growing group of nontuberculous mycobacteria more common in patients with genetic or acquired causes of immune deficiency. There have been few published reports of Mycobacterium fortuitum associated with breast infections mainly associated with breast implant and reconstructive surgery. Case presentation We report a case of a 51-year-old Caucasian woman who presented to our one-stop breast clinic with a two-week history of left breast swelling and tenderness. Following triple assessment and subsequent incision and drainage of a breast abscess, the patient was diagnosed with Mycobacterium fortuitum and treated with antibiotic therapy and surgical debridement. Conclusion This is a rare case of a spontaneous breast abscess secondary to Mycobacterium fortuitum infection. Recommended treatment is long-term antibacterial therapy and surgical debridement for extensive infection or when implants are involved.

    The study was conducted with an objective to investigate the association between reproductive factors, nutritional status and serum 25(OH)D levels among women diagnosed with breast cancer (BC). A total of 200 women with BC attending a tertiary healthcare institute of Delhi, India matched with 200 healthy women for age (±2years) and socio economic status were included in the study. Data was collected on socio-demographic profile, reproductive factors, physical activity and dietary intake (24h dietary recall and food frequency questionnaire) using interviewer administered structured questionnaires and standard tools. Non fasting blood samples (5ml) were collected for the biochemical estimation of serum 25(OH)D and calcium levels by chemiluminescent immunoassay and colorimetric assay technique. Data was analyzed by univariable conditional logistic regression and significant variables with (p<0.05), were analyzed in final model by conditional multivariable logistic regression analysis. The mean age of patients at diagnosis of BC was 45±10years. Results of multivariable conditional logistic regression analysis revealed significantly higher odds of BC for reproductive factors like age at marriage (more than 23 years), number of abortions, history or current use of oral contraceptive pills (OCP), with [OR (95% CI)] of [2.4 (1.2-4.9)], [4.0 (1.6-12.6)], [2.4 (1.2-5.0)]. Women with physically light activities and occasional consumption of eggs were found to have higher odds of BC [4.6 (1.6-13.0)] and [3.2 (1.6-6.3)]. Women with serum 25(OH)D levels less than 20ng/ml and calcium levels less than 10.5mg/dl had higher odds of having BC [2.4 (1.2-5.1)] and [3.7 (1.5-8.8)]. A protective effect of urban areas as place of residence and energy intake greater than 50% of Recommended Dietary Allowance (RDA) per day against BC was observed (p<0.05). The findings of the present study revealed a significant association of reproductive and dietary factors in addition to sedentary

    Being diagnosed with breast cancer is devastating for women because they face a "sense of loss". Since this loss is observed by the women themselves as well as by those around them, this can often lead to depression. (1) To verify a possible association between body image and depression; (2) To establish a relation between depression and time since breast cancer diagnosis. The data came from the Beck Depression Inventory (BDI-II) and the Body Image Scale (BIS), which were used to evaluate the subjects. A random sample of n=120 women was divided into two groups. The women in Group 1 had been recently diagnosed with breast cancer, but had not at that time had any type of surgical treatment. The women in Group 2 had undergone a mastectomy over a year ago. The women in Group 1 were found to be more severely depressed, and a statistically significant association was detected between depression and body image (p0.05). The women in Group 1, the majority of whom were suffering from severe depression, had a disturbed body image even though they had not had a mastectomy. The women in Group 2, who had been operated, also suffered from similar body image problems, but their depression was not as intense. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

    Background: Previously published data on any association of the fat mass and obesity-associated (FTO) gene with breast cancer risk remain inconclusive. Therefore, we conducted the present meta-analysis of links between breast cancer and the FTO rs9939609 polymorphism. Methods: We have conducted a systematic review of the English literature by searching PubMed, Google Scholar and ISI Web of Knowledge databases for studies on associations between the FTO rs9939609 polymorphism and breast cancer risk. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate the strength of the association using fixed- or random-effects model. Results: We included five studies with 1134 cases and 1453 controls. Overall, no significant association between the FTO rs9939609 polymorphism and risk of breast cancer was found. On subgroup analysis by ethnicity, there was still no significant association detected. Conclusions: To our knowledge, this is the first meta-analysis of the FTO rs9939609 polymorphism and risk of breast cancer. However, the present meta-analysis suggested that only there might be a significant association of the CXCL12 rs1801157 polymorphisms with breast cancer risk. Creative Commons Attribution License

  20. Impact of tetrachloroethylene-contaminated drinking water on the risk of breast cancer: Using a dose model to assess exposure in a case-control study

    2005-02-01

    Full Text Available Abstract Background A population-based case-control study was undertaken in 1997 to investigate the association between tetrachloroethylene (PCE exposure from public drinking water and breast cancer among permanent residents of the Cape Cod region of Massachusetts. PCE, a volatile organic chemical, leached from the vinyl lining of certain water distribution pipes into drinking water from the late 1960s through the early 1980s. The measure of exposure in the original study, referred to as the relative delivered dose (RDD, was based on an amount of PCE in the tap water entering the home and estimated with a mathematical model that involved only characteristics of the distribution system. Methods In the current analysis, we constructed a personal delivered dose (PDD model that included personal information on tap water consumption and bathing habits so that inhalation, ingestion, and dermal absorption were also considered. We reanalyzed the association between PCE and breast cancer and compared the results to the original RDD analysis of subjects with complete data. Results The PDD model produced higher adjusted odds ratios than the RDD model for exposures > 50th and >75th percentile when shorter latency periods were considered, and for exposures th and >90th percentile when longer latency periods were considered. Overall, however, the results from the PDD analysis did not differ greatly from the RDD analysis. Conclusion The inputs that most heavily influenced the PDD model were initial water concentration and duration of exposure. These variables were also included in the RDD model. In this study population, personal factors like bath and shower temperature, bathing frequencies and durations, and water consumption did not differ greatly among subjects, so including this information in the model did not significantly change subjects' exposure classification.

    Spontaneous breast infarction is a very rare complication of fibroadenoma of the breast. We present an interesting case of a 33-year-old woman with spontaneous infarction of hyperplastic breast tissue related to pregnancy and lactation. Mammography showed an oval, circumscribed, fat-containing mass with microcalcifications. Ultrasonography revealed an oval, circumscribed mass with echogenic dots. Color Doppler imaging revealed presence of minimal vascularity at the periphery of the mass.

    D-penicillamine, a chelating agent of copper, is the drug of choice for the treatment of Wilson's disease. Breast enlargement is a rare complication arising from its use, and we report a case of breast gigantism which developed after it had been used for ten months to treat this condition. Mammography demonstrated bilaterally enlarged dense breasts; ultrasonography, similarly, demonstrated enlargement, revealing the presence of a mass, shown at biopsy to be benign, in the left one.

    Preoperative breast magnetic resonance (MR) imaging features of primary breast cancers may have the potential to act as prognostic biomarkers by providing morphologic and kinetic features representing inter- or intra-tumor heterogeneity. Recent radiogenomic studies reveal that several radiologist-annotated image features are associated with genes or signal pathways involved in tumor progression, treatment resistance, and distant metastasis (DM). We investigate whether preoperative breast MR imaging features are associated with worse DM-free survival in patients with invasive breast cancer. Of the 3536 patients with primary breast cancers who underwent preoperative MR imaging between 2003 and 2009, 147 patients with DM were identified and one-to-one matched with control patients (n = 147) without DM according to clinical-pathologic variables. Three radiologists independently reviewed the MR images of 294 patients, and the association of DM-free survival with MR imaging and clinical-pathologic features was assessed using Cox proportional hazard models. Of MR imaging features, rim enhancement (hazard ratio [HR], 1.83 [95% confidence interval, CI 1.29, 2.51]; p = 0.001) and peritumoral edema (HR, 1.48 [95% CI 1.03, 2.11]; p = 0.032) were the significant features associated with worse DM-free survival. The significant MR imaging features, however, were different between breast cancer subtypes and stages. Preoperative breast MR imaging features of rim enhancement and peritumoral edema may be used as prognostic biomarkers that help predict DM risk in patients with breast cancer, thereby potentially enabling improved personalized treatment and monitoring strategies for individual patients.

    Full Text Available Breast cancer in African-American (AA women occurs at an earlier age than in European-American (EA women and is more likely to have aggressive features associated with poorer prognosis, such as high-grade and negative estrogen receptor (ER status. The mechanisms underlying these differences are unknown. To address this, we conducted a case-control study to evaluate risk factors for high-grade ER- disease in both AA and EA women. With the onset of the Health Insurance Portability and Accountability Act of 1996, creative measures were needed to adapt case ascertainment and contact procedures to this new environment of patient privacy. In this paper, we report on our approach to establishing a multicenter study of breast cancer in New York and New Jersey, provide preliminary distributions of demographic and pathologic characteristics among case and control participants by race, and contrast participation rates by approaches to case ascertainment, with discussion of strengths and weaknesses.

    Hamartoma of the breast is an uncommon, benign, slow-growing mass usually diagnosed in women in the fourth and fifth decade of life undergoing mammography (MX). Here we report two cases of hamartoma of the breast assessed by integrated MX, ultrasonography and magnetic resonance imaging (MRI) examination. Case 1 was an asymptomatic 47-year-old woman who had never been screened previously. A 90 mm mass was found in her left breast on MX. Case 2 was a 35-year-old woman with pain in her right breast where a 50 mm mass was found on MX. Both patients underwent MRI examination. Breast MRI is an adjunct to MX that can confirm hamartoma diagnosis and exclude rare malignant transformation.

    Full Text Available Many oncological drugs that are being used in the adjuvant setting were first submitted for reimbursement in the metastatic stage, with differences in incremental cost-effectiveness ratios (ICERs in both settings having potential implications for reimbursement and pricing. The aim of this study is to identify a possible trend in the cost-effectiveness for the early/adjuvant and late/metastatic stages of oncological drugs through review and case study.We reviewed pairs of cost-effectiveness analyses of the same oncological drug in different stages for Scotland and the Netherlands. The case study in this report was directed at trastuzumab in the Dutch situation. Using a simplified Markov model, the cost-effectiveness in early and late stage of breast cancer was calculated and compared to the findings from the review.Comparable studies were found for cetuximab, bortezomib and bosutinib. Treatments in the late stage were found to be more expensive per QALY by a factor ranging from 1.5 to 12. The case study provided a similar result; late stage treatment was more expensive by a factor 10. Using, for example, a threshold of € 80,000/QALY, the early stage of cetuximab, bosutinib and trastuzumab are deemed cost-effective, while their compared late stage is lifted over the threshold and potentially considered not cost-effective.ICERs of oncological drugs used in different stages are more unfavourable in the late stage than in the early stage. Applying a reasonable threshold may result in early stage treatment being deemed cost-effective while late stage potentially not. Authorities should be aware of this when assessing oncological drugs and interpreting the corresponding ICERs, in the situation where oncological drugs are generally most submitted for reimbursement in the late stage initially.

    Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematologic tumor that typically occurs in older adults. Patients with BPDCN usually present with solitary or multiple skin lesions. Localized or disseminated lymphadenopathy at presentation is common. A case report illustrating histopathologically proven BPDCN initially misdiagnosed as breast infiltrating ductal carcinoma in a 39-year-old woman is presented. In this case, the patient presented with a breast mass without an obvious skin lesion initially. The morphology of the tumor cells mimicked high grade breast carcinoma cells. Without complete immunohistochemical study, this case was initially misdiagnosed as infiltrating ductal carcinoma. Reviewing the previous literature about BPDCN, no case with a breast mass and an absence of characteristic skin lesions initially has been reported. The purpose for which we are discussing this case is to reduce misdiagnosis when the initial symptom is unusual. © The Author(s) 2014.

    Oncoplastic breast conserving surgery (OBCS) allows women who may otherwise have mastectomy and immediate reconstruction (MxIR) the choice to conserve their breast yet avoid deformity. We compared the outcome of these options. Two cohorts meeting study criteria were identified from prospectively audited series of women undergoing OBCS or MxIR. After case matching for age, tumour size and date of surgery, stratification by breast size and controlling for radiotherapy; body image scale (BIS) scores of psychosocial function and patient reported outcome measures (PROMs) for breast appearance and return to function were analysed. A total of 567 women (286 treated by OBCS and 281 by MxIR) fulfilled inclusion criteria. Demographics were similar between the two unmatched cohorts, except for radiotherapy, age and tumour size (all p breast appearance, return to work and function (all p breasts treated by OBCS reported better BIS scores (mean 3.30 vs. 5.37, p = 0.011) and self-rated breast appearance score (p breasts. BIS and appearance favoured OBCS, regardless of whether radiotherapy would have been avoided if treated by MxIR. OBCS offers suitable women the option to avoid MxIR while providing faster recovery. Better psychosocial and self-rated satisfaction with breast appearance is achieved for OBCS in all groups, regardless of the need for radiotherapy, apart from those women with smaller breasts for whom the results are comparable.

    Primary leiomyosarcoma of the breast is an extremely rare tumor, accounting for less than 1% of all breast tumors and only 24 cases have been reported in the English medical journals. It is quite difficult to diagnose leiomyosarcoma preoperatively. Establishing an accurate diagnosis is very important in planning treatment. When preoperative diagnosis can be achieved before or during the operation, wide resection should be performed. There is no need for axillary lymph node dissection. In this case report, we present a case involving primary leiomysarcoma of the breast in a 48-year-old woman and we discuss optimal treatment options. PMID:22493639

    Full Text Available BACKGROUND Worldwide, breast cancer is the most frequent cancer in women and represents the second leading cause of cancer death among women. Locally advanced breast cancer constitutes more than 50-70% of the patients presenting for treatment has two common problems in treatment. Achieving local control and prolonging survival by preventing or delaying distant metastasis. Today, treatment of LABC requires a combination of systemic and local/regional therapies. The aim of the study is to study the clinicopathological presentation, age distribution and various modes of management of locally advanced breast carcinoma. Worldwide breast cancer is the most frequent cancer in women and represents the second leading cause of cancer death among women. Locally advanced breast cancer constitutes more than 50-70% of the patients presenting treatment. MATERIALS AND METHODS The present study includes 50 patients who attended Department of General Surgery for a period of three years. RESULTS The patients were regularly followed up and at the end of the study 35 (70% of the patients were doing well. 4(8% of the patients developed distant metastasis and 3 (6% of the patients developing local recurrence. 8 (16% of the patients were lost follow up. CONCLUSION About half of the cases presenting with breast cancer are in locally advanced stages. Multimodality therapy is the effective treatment of locally advanced carcinoma of breast. Breast cancer management is a challenge and improvement in therapies are needed for disease-free interval and overall survival period.

    Little is known about risk factors for pregnancy-associated breast cancer (PABC), diagnosed during pregnancy or postpartum. We enrolled 1715 premenopausal women from the Nigerian Breast Cancer Study from 1998 to 2011. Based on recency of last pregnancy from diagnosis, breast cancer cases were categorized as (1) PABC diagnosed 2 years or longer postpartum, (2) PABC diagnosed 3 to 5 years postpartum, or (3) non-PABC diagnosed more than 5 years postpartum. Controls were matched to cases on recency of last pregnancy. Multiple logistic regressions were performed comparing cases and controls within each group. Of the 718 cases, 152 (21.2%) had PABC 2 or more years postpartum, and 145 (20.2%) 3 to 5 years postpartum. Although not statistically significant, women with higher parity tend to have an elevated risk of PABC but reduced risk of non-PABC (p for heterogeneity = 0.097). Family history of breast cancer might be a strong predictor particularly for PABC 2 or more years postpartum (odds ratio, 3.28; 95% confidence interval, 1.05-10.3). Compared with non-PABC cases, PABC 2 or more years postpartum cases were more likely to carry BRCA1/2 mutations (P = .03). Parity may have different roles in the development of PABC versus other premenopausal breast cancer in Nigerian women. Prospective mothers with multiple births and a family history of breast cancer may have an elevated risk of breast cancer during their immediate postpartum period. Copyright © 2013 Elsevier Inc.

    Phyllodes tumor is a rare fibro epithelial neoplasm of the breast. They resemble fibroadenomas clinically and can be mistakenly ignored sometimes. We report the case of a young woman with her first presentation to hospital due to a hypoglycemia and she underwent 2 excised fibroadenomas in the same breast before diagnosed of malignant phyllodes tumor. She was complaining about 2 masses presented in her right breast 4 months after mastectomy. Recurrent phyllodes tumor of the breast. We conducted an immediate autologous myocutaneous flap transplantation after a wide-excision. Postoperative radiotherapy was recommended. She was in good general condition without tumor relapses during 8 months of follow-up. Recurrent fibroadenomas in the same breast, especially those of large size with rapid growth rate, suggesting a high transformation possibility from fibroadenoma to phyllodes tumor. We recommend an extended tumor resection and immediate or delayed reconstruction of the breast for the recurrent phyllodes tumor with separately multiple relapses.

    Full Text Available Dermatofibrosarcoma protuberans is a cutaneous soft tissue neoplasm with potential for local recurrence but distant metastasis is rare. Trunk and extremities are most commonly involved. This case presented as left-sided breast lump in a male patient. The patient underwent left-sided modified radical mastectomy. Tissues were subjected to histopathological and immunohistochemical test subsequently. The tumor cells showed storiform arrangement with nuclear pleomorphism and increased mitotic figures at places. They were reactive to CD34 and non-reactive to S-100, smooth muscle actin, desmin, cytokeratin and epithelial membrane antigen. The diagnosis of dermatofibrosarcoma protuberans with areas of fibrosarcomatous change was given. Though trunk is a common site for this tumor but its presentation as male breast lump has made the case unique.

    Full Text Available Oral contraceptives are known to influence the risk of cancers of the female reproductive system. Evidence regarding the relationship between injectable contraceptives and these cancers is limited, especially in black South Africans, among whom injectable contraceptives are used more commonly than oral contraceptives.We analysed data from a South African hospital-based case-control study of black females aged 18-79 y, comparing self-reported contraceptive use in patients with breast (n = 1,664, cervical (n = 2,182, ovarian (n = 182, and endometrial (n = 182 cancer, with self-reported contraceptive use in 1,492 control patients diagnosed with cancers with no known relationship to hormonal contraceptive use. We adjusted for potential confounding factors, including age, calendar year of diagnosis, education, smoking, alcohol, parity/age at first birth, and number of sexual partners. Among controls, 26% had used injectable and 20% had used oral contraceptives. For current and more recent users versus never users of oral or injectable contraceptives, the odds ratios (ORs for breast cancer were significantly increased in users of oral and/or injectable contraceptives (OR 1.66, 95% CI 1.28-2.16, p<0.001 and separately among those exclusively using oral (1.57, 1.03-2.40, p = 0.04 and exclusively using injectable (OR 1.83, 1.31-2.55, p<0.001 contraceptives; corresponding ORs for cervical cancer were 1.38 (1.08-1.77, p = 0.01, 1.01 (0.66-1.56, p = 0.96, and 1.58 (1.16-2.15, p = 0.004. There was no significant increase in breast or cervical cancer risk among women ceasing hormonal contraceptive use ≥10 y previously (p = 0.3 and p = 0.9, respectively. For durations of use ≥5 y versus never use, the ORs of ovarian cancer were 0.60 (0.36-0.99, p = 0.04 for oral and/or injectable contraceptive use and 0.07 (0.01-0.49, p = 0.008 for injectable use exclusively; corresponding ORs for endometrial cancer were 0

    Intracystic papillary carcinoma of the breast (ICP) is a rare form of noninvasive breast cancer. The average age of onset is 65 years. Patients with ICP have a greater than 15-year survival rate advantage compared to patients with other breast carcinomas. There have been no reports of disease-related deaths in patients with ICP and no increased risk of disease in the contralateral breast. No definitive conclusions have been made regarding adjuvant treatment; however, ICP should generally be treated like ductal carcinoma in situ (DCIS). Tamoxifen is often recommended.

    All known cases of breast cancer in patients with a diagnosis consistent with transgender identification were identified in the Veterans Health Administration (1996-2013). Ten cases were confirmed: seven birth sex females and three birth sex males. Of the three birth sex males, two identified as gender dysphoric male-to-female and one identified as transgender with transvestic fetishism. The birth sex males all presented with late-stage disease that proved fatal, whereas most of the birth sex female transgender veterans presented with earlier stage disease that could be treated. These cases support the importance of screening for breast cancer using standard guidelines in birth sex males and females. Family history of breast cancer should be obtained from transgender people as part of routine care. This report expands the known cases of breast cancer in transgender persons from 5 to 12 (female-to-male) and from 10 to 13 (male-to-female).

Conclusão: o câncer de mama associado à gravidez mantém-se como neoplasia de mau prognóstico, não havendo diferença quando se compara com pacientes não grávidas para a mesma média de faixa etária, sendo que o fator determinante na sobrevida é o estádio clínico avançado no momento do diagnóstico.Purpose: to report 15 breast cancer cases associated with pregnancy and to compare to a control group with breast ductal infiltrating carcinoma, evaluating clinical staging, metastatic axillary lymph node involvement, histopathologic aspects related to nuclear grade, histology grade and estrogen and progesterone hormonal receptors. Method: a retrospective study of 15 cases of patients with breast cancer associated with pregnancy, attended at Mastology Department in the Woman Health Reference Center, Pérola Byington Hospital, São Paulo, was done between September 1996 and April 2001. The evaluation of clinical staging, time of diagnosis and involved axillary lymph nodes was the main study basis. Also age, parity, histologic type, applied treatment, histologic characteristics regarding nuclear grade and histologic grade and the presence of hormonal receptors in the tumors were analyzed. Results: we observed that 7 patients (46.7% presented a locally advanced breast cancer (clinical stage IIIA and IIIB and that 3 patients (20% presented a disseminated disease at the moment of diagnosis. The patients presented on average 2.4 involved axillary lymph nodes and in only one patient the lymph nodes were free of disease (6.6%. Regarding time of diagnosis, 40% of the tumors were diagnosed during the lactational period, 46.7% during the second trimester and 13.3% during the third trimester. The pregnant patients were compared to a control

  5. The evolution of FDA policy on silicone breast implants: a case study of politics, bureaucracy, and business in the process of decision-making.

    Palley, H A

    1995-01-01

    The central issue facing federal regulation of breast implants is that while such devices are not functionally necessary or needed for survival, the side effects may be harmful and have not been proven unharmful. The Medical Device Amendments of 1976 appear to require such evidence prior to the FDA permitting the unrestricted marketing of these devices. However, only recently have such requirements been imposed by the FDA. The author examines the FDA's decision-making process, particularly as applied to silicone breast implants, and the factors that appears to have affected such decisions. In pursuing this study, the activities of a number of interest-group actors, as well as congressional responses and the role of federal bureaucratic actors, were examined. In 1992, the FDA established a regulatory protocol that effectively withdrew most silicone breast implants from the market for the purpose of breast augmentation and allows for the monitoring of the impact of new implants on women's health. This increase concern for determining the safety of breast implants is due to a number of factors, which are examined in this article.

    Kermanshahi oil is one the most favorable oils in Iran especially in Kermanshah province. We aimed to evaluate the role of usual intake of Kermanshahi oil and other kinds of dietary fats as well as different meats, vegetables and fruits, carbohydrates, cereals, grains, sweets, candy and lifestyle habits in risk of breast cancer. A case-control study with 47 consecutive, newly diagnosed premenopausal breast- cancer patients and 105 age and socioeconomic matched healthy women was conducted from 2013-2014 in Imam Reza hospital of Kermanshah using a standardized, validated questionnaire assessing various anthropometric, socio-demographic, lifestyle and dietary characteristics. Kermanshahi oil intake was associated with a 2.1-fold (OR= 2.123, 95% CI 1.332- 3.38) (p= 0.002) higher likelihood of having breast cancer, while daily intake of other solid animal fats also increased the likelihood by 2.8-fold (OR = 2.754, 95% CI 1.43- 5.273) (p cancer risk in this region. This study suggested that animal fat increases the risk of premenopausal breast cancer but many other dietary and non-dietary factors including calcium and vitamin D deficiency are consistently associated with increased odds of breast cancer in this region.

    A crucial issue in healthcare is how multidisciplinary teams can use indicators for quality improvement. Such teams have increasingly become the core component in both care delivery and in many quality improvement methods. This study aims to investigate the relationships between (1) team factors and the way multidisciplinary teams use indicators for quality improvement, and (2) both team and process factors and the intended results. An in-depth, multiple-case study was conducted in the Netherlands in 2008 involving four breast cancer teams using six structure, process and outcome indicators. The results indicated that the process of using indicators involves several stages and activities. Two teams applied a more intensive, active and interactive approach as they passed through these stages. These teams were perceived to have achieved good results through indicator use compared to the other two teams who applied a simple control approach. All teams experienced some difficulty in integrating the new formal control structure, i.e. measuring and managing performance, in their operational task, and in using their 'new' managerial task to decide as a team what and how to improve. Our findings indicate the presence of a network of relationships between team factors, the controllability and actionability of indicators, the indicator-use process, and the intended results.

    The aim of this case-control study was to compare two different statistical methods in the identification of dietary patterns by use of principal component analysis (PCA) and variable clustering (VC) and to examine their association with the risk of breast cancer (BC). A dose-response association was then performed by the use of an adaptation of free knot spline function in logistic models. A "Western" pattern was revealed by PCA and VC and was then shown to be associated with a nonsignificant increase of BC risk. Only PCA identified a "meat/alcohol" pattern. Above the spline threshold, BC risk increased significantly (OR ≥ s vs. association between BC risk and this pattern was shown. VC split the "Mediterranean" dietary pattern in two: "raw vegetables and olive oil" and "fish." Above the spline threshold, the "fish" pattern tended to protect against BC risk (OR ≥ s vs. < s = 0.77, 95% CI 0.58-1.01), whereas an excess of raw vegetables and olive oil increased BC risk (OR 1 se = 1.22, 95% CI = 1.06-1.32). Some results from the PCA and the VC methods were similar, whereas others were different but gave complementary results. Copyright © 2012 Elsevier Inc. All rights reserved.

    Phyllodes tumor of the breast is a rare biphasic neoplasm, accounting for less than 1% of all breast tumors. Coexistence of phyllodes tumor and breast cancer in distinct breasts is extremely rare. A 47-year-old Japanese woman presented with bilateral breast lumps. A HER2-positive, unresectable invasive carcinoma in the right breast and fibroadenoma in the left were diagnosed via core needle biopsy. During chemotherapy with anti-HER2 therapy, the breast cancer shrank quickly, while the left breast lump suddenly enlarged. Under a diagnosis of malignant neoplasm of the breast, left mastectomy was performed. Malignant phyllodes tumor was diagnosed by postoperative histological examination and recurred in multiple areas as early as 2 months after surgery. Only 10 cases of coexisting phyllodes tumor and breast cancer in distinct breasts have been reported in the English literature. Phyllodes tumor associated with breast cancer in distinct breasts tends to be malignant. This is the first case of phyllodes tumor rapidly enlarging during anti-HER2 chemotherapy for locally advanced HER2-positive breast cancer. Even during effective treatment of advanced or recurrent breast cancer, attention should also be paid to the contralateral breast for the possible association of a second malignancy such as phyllodes tumor.

    The relation between scoring for hopelessness/helplessness and the Montgomery-Asberg Depression Rating Scale (MADRS) in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared in a prospective study. We, therefore, investigated hopelessness and helplessness scores versus the MADRS in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness, and for the MADRS before any diagnostic procedures were carried out. In the self-rating score (SRS), hopelessness/helplessness versus the MADRS were highly significantly positively correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa values for hopelessness/helplessness versus the MADRS in the HSS, BBD and BC groups were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) for hopelessness versus the MADRS in the HSS, BBD and BC groups and for helplessness versus the MADRS in the HSS, BBD and BC groups. The unweighted kappa values in the ERS for hopelessness versus the MADRS were statistically highly significant for the HSS, BBD and BC groups and those for helplessness versus the MADRS in the HSS and BBD groups were statistically significant. A new finding with clinical relevance in the present work is the agreement between hopelessness/helplessness scores and MADRS in the SRS and ERS. In the breast cancer diagnostic unit, the identification of hopeless/helpless persons is essential in suicide prevention and it is important to assess and treat hopelessness/helplessness even though an individual may report few depressive symptoms.

    A single case is reported utilizing, recipient site pre-expansion with BRAVA (Brava, Inc, Miami, FL) followed by autologous fat grafting to the breast in a patient with severe breast asymmetry. Recipient site pre-expansion, used 2 to 3 weeks before fat grafting and 2 weeks after fat grafting may have both practical and theoretical benefits in optimizing the volume and enhancing the survival of grafted adipocytes, the mechanism of which is discussed. Recipient site pre-expansion and fat grafting may have early clinical adoption in cases of severe asymmetry, tuberous breasts, and other deformities that are difficult to treat with current reconstructive techniques, but studies are needed to clearly delineate its safety and its role.

    2013-01-01

    Background: To study the patterns of clinically benign breast disease in females and to co-relate them with the pathological findings. Methods: One hundred females who attended the Surgery Outpatients Department in Indira Gandhi Medical College and Research Institute, Pondicherry, with various forms of benign breast diseases during the period from October 2011 to September 2012, were studied. Early diagnoses by doing a triple assessment like a clinical examination, FNAC or a core needle biopsy and imaging methods like ultrasonography or mammography, were made within 72 hrs from the first consultation. The clinical diagnoses were compared with the cytological or histological findings wherever possible and their accuracies were evaluated. Results: Out of the 100 female patients who were studied, 87 patients who presented with breast lumps and fibroadenoma, accounted for 48% of the cases, which was the highest number of patients. Fibrocystic changes and breast abscesses came next with 18% and 12% cases respectively. We detected 3 cases of proliferative disease with atypia and one case with florid hyperplasia, which had high and low risk factors respectively, for developing invasive carcinoma. The oldest lady of the group who was clinically diagnosed to have benign disease, was detected to have invasive ductal carcinoma. They were treated in our hospital and were advised follow up. Conclusion: Benign breast diseases are common in female patients and fibroadenoma is the commonest of them all. Triple assessment provided a quick diagnosis and it alleviated unnecessary anxiety from the patients about breast cancer. The clinical diagnosis of a breast lump, as confirmed by cytology and histology, was accurate in 91.95 % of the cases. PMID:23634406

    Breast cysts are mainly benign and are reported in association with fibrocystic disease and phyllodes tumor. Rarely have cystic changes been reported to occur in malignant tumors. They are usually small but large in rare cases. Giant breast cysts are very rare, and only a few cases have been reported. A 37-year-old woman presented with a rapidly growing breast mass. Mammography showed a huge, well-circumscribed cystic mass (17 x 16 x 16 cm) suggestive of a benign lesion. Cytologic examination revealed a highly cellular tumor composed of malignant cells of various sizes and shapes in a necrotic background. The smears were diagnosed as positive for malignancy and suggested metaplastic carcinoma. Mastectomy was performed, and histologic study confirmed the cytologic diagnosis. This is the first reported case of a breast cyst of this size. Clinically the cyst was confused with a benign lesion. The fine needle aspiration aided the diagnosis and planning of treatment.

    Full Text Available Background : Fine needle aspiration cytology (FNAC has a high rating in the assessment of breast lesions. Various methods have been used to diagnose cytology of breast lesions. Aims : Present study was undertaken to evaluate the feasibility of application of systematic pattern analysis based on morphology in diagnosing breast aspirates. Materials and Methods : This is a retrospective study of FNAC of the breast done over a period of 4 years in a tertiary care centre. A total of 225 cases of breast lesions for which FNAC was done with histological follow-up were included in the study. Breast aspirates were provisionally diagnosed based on systematic pattern analysis. Aspirates were grouped into six categories based on predominant cellular pattern, and correlation between cytological and histological diagnosis was assessed. Results : Application of pattern analysis on FNAC of breast lesions in our study had a sensitivity of 94.5%, specificity of 98%, diagnostic accuracy of 97%, positive predictive value of 95.8%, and negative predictive value of 97.4%. Conclusions : Systematic pattern analysis based on morphology of FNAC smears was found to be highly reliable and could be easily reproducible in the assessment of breast masses.

    An unorthodox method of casing drilling used by Tesco Corporation at a gas well in Wyoming to drill deeper using casings as drillpipe is discussed. The process involves either rotating the casing as drill string or using a downhole mud motor to rotate the bit. In this instance, the surface hole and the production hole were casing-drilled to a record 8,312 feet by rotating the casing. The 8 1/2-inch surface hole was drilled with 7-inch casing to 1,200 feet using a Tesco underreamer and a polycrystalline pilot bit; drilling and cementing was completed in 12 1/2 hours. The 6 1/4-inch production hole was drilled with 4 1/2-inch casing and the bottomhole assembly was retrieved after 191 hours rotating. This case was the first in which the entire well was casing-drilled from surface to TD. Penetration rate compared favorably with conventional methods: 12 1/2 hours for casing-drilling to 18.9 hours for conventional drilling, despite the fact that the casing-drilling technology is still in its infancy. It is suggested that casing-drilling has the potential to eliminate the need for the drillpipe entirely. If these expectations were to be realised, casing-drilling could be one of the most radical drilling changes in the history of the oil and gas industry. 1 photo.

    Metaplastic breast carcinoma (MBC) is a rare type of breast cancer. Osseous differentiation is a very rare subtype. Reporting this kind of case is important because its clinical course and line of management are poorly mentioned in the literatures. We present a very rare case of MBC with osseous differentiation. A 48-year-old female presented with painless hard mass of the left breast. Examination and investigations showed MBC with osseous differentiation. She was managed by operation with adjuvant chemotherapy. MBC with osseous differentiation is a very rare type of breast carcinoma presenting with hard mass and managed by mastectomy, axillary lymph node sampling and adjuvant chemotherapy.

    The incidences of both thyroid cancer and breast cancer have been rising in recent years; however, it is very rare to find a single person with both of these cancers. Only a few cases of synchronous thyroid and breast cancer have been published, and even fewer cases have been reported in older patients (>60 years). The current study presents a case of synchronous papillary thyroid carcinoma and breast ductal carcinoma in an elderly patient. The patient first underwent a mastectomy and axillary lymphadenectomy in our department, followed by a total thyroidectomy and lymphadenectomy of the left lateral region of the neck 1 month later. Postoperative pathological examination identified invasive ductal carcinoma of the breast and papillary carcinoma of the thyroid. Over almost half a year of follow-up, the patient has exhibited no evidence of recurrence or metastasis, as demonstrated by careful ultrasound examinations. Herein, we not only report this case but also present a systematic review of the causes, diagnosis, and treatment of synchronous breast and thyroid cancer. Although synchronous primary tumors of the thyroid and breast are very rare, they remain a possibility; therefore, more attention should be paid to these cases.

    Primary leiomyosarcoma of the breast is an extremely rare tumor, accounting for less than 1% of all breast tumors and only 24 cases have been reported in the English medical journals. It is quite difficult to diagnose leiomyosarcoma preoperatively. Establishing an accurate diagnosis is very important in planning treatment. When preoperative diagnosis can be achieved before or during the operation, wide resection should be performed. There is no need for axillary lymph node dissection. In this...

    Accurate evaluation of human epidermal growth factor receptor 2 (HER2) status is quite crucial for invasive breast tumor patients in order to select anti-HER2 therapy for effective clinical outcomes. Immunohistochemistry (IHC) assay is routinely used to evaluate the HER2 oncoprotein overexpression but is unable to explain the chromosomal and genetic alterations and has been considered as a hot issue in IHC-equivocal cases. We investigated these molecular aberrations in correlation with prognostic factors. A cohort of 154 IHC-equivocal (+2) cases was selected and retrospectively analyzed by dual-probe fluorescence in situ hybridization (FISH) assay by using locus-specific HER2 and centromere enumeration probes (CEP17) for the identification of HER2 proto-oncogene amplification and chromosomal copy number per cell, respectively. The data were analyzed by SPSS 16.0 version using chi-square test (p cases (23.4 %) showing HER2 gene amplification (average HER2 gene copies per cell >4 or 2) in concordance with HER2 oncoprotein overexpression, and significant correlation was observed with prognostic parameters including histological type, tumor grade II to III, histology and pathological type, lymphatic invasion, ductal carcinoma in situ (DCIS), and estrogen-positive and progesterone-negative receptors. Of the 154 cases, 18 cases (11.7 %) showed polysomy 17 with CEP17 probe signals per cell ≥3 and 22 cases (14.3 %) presented monosomy 17 (CEP17 probe signals per cell ≤1). Our data indicate that the use of anti-HER2 therapy should not be suggested unless true evaluation of HER2 protein expression is made regarding gene amplification essentially in IHC-ambiguous invasive breast tumors.

    In recent years, patients with orthognathic surgery in middle-aged and elderly people have come to be a more frequent occurrence. Breast cancer is the most frequently diagnosed cancer in woman worldwide, and its prevalence rate is steadily increasing. We report a case of a 47-year-old Japanese woman in whom left-side breast cancer (Stage 1) was unexpectedly found just before orthognathic surgery in April 2012. Breast-conserving surgery was performed (estrogen receptor+, progesterone receptor+, HER2 -, surgical margin+, sentinel lymph node +) that May. From June to August docetaxel (75mg/m2) and cyclophosphamide (600mg/m2) were administrated four times every 21days and thereafter radiotherapy (total 60Gy) was completed. The cancer surgeon declared the prognosis good and the patient had a strong desire to undergo orthognathic surgery, so in November we performed a bimaxillary osteotomy, and administration of tamoxifen began 6 weeks after the osteotomy. There are breast cancer cases in which the prognosis is sufficiently good for a planned orthognathic surgery to proceed. Good communication among surgeons and the patient is important. We experienced a case in which breast cancer was found just before the orthognathic surgery; we performed a bimaxillary osteotomy, including follow-up tamoxifen administration, during breast cancer treatment.

    Full Text Available Carcinoma of the breast is one of the commonest cancers occurring in female and accounts for 1/3rd of all the malignant diseases occurring in them. It is mainly a disease of the developed countries and accounts for 1,00,000 deaths annually. Breast carcinoma is classified as Early breast cancer, Locally advanced breast cancer and Metastatic breast cancer. By definition early stage breast cancer constitutes breast tumors of clinical stages I, IIa and T2N1M0. Early breast cancer is the one diagnosed by mammography. Women when approaches at this stage, they can go for breast conservation surgery. Not all women are candidates for this approach, and some require mastectomy as part of their treatment. AIM To observe the incidence of early breast carcinoma with particular reference to the time taken by the patients to seek medical advice after the symptoms have developed i.e. the average time taken by the patients to seek medical advice, their appropriate management and prognosis. MATERIALS AND METHODS This prospective study was conducted over a period of 2 years from Oct-2012 to Oct-2014 in 30 female patients aged between 25-65 years who were presented with lump in breast of size ≤5cms with or without pain, with or without lymph nodes to the outpatient department. All the patients were thoroughly asked about history, examined clinically, investigated, staged and managed by surgery either Breast Conservation Surgery or Modified Radical Mastectomy. Postoperative complications were recorded and followed up regularly. RESULTS The incidence of early breast cancer in this study was 0.98% with peak age incidence between 40-60 years and duration of symptoms <6 months in 18 patients. Breast Conservation Surgery + axillary dissection + Radiotherapy was done in 23%. Prognosis was good in these patients with no local recurrence and death. CONCLUSION The prognosis of early stage breast carcinoma patients in this study was good. To have long term tumor free and

    This study was aimed at determining whether the familial clustering often observed in breast cancer is associated with genetic factors. We compared familial and sporadic breast cancer cases with respect to ABO blood group distribution and the risk of bilateral disease, using the data from the Icelandic Cancer Registry which contains genealogical information for about 30% of the breast cancer cases diagnosed in Iceland since 1911. Cases were classified as familial if at least one first-degree relative had breast cancer. Using this criterion, we identified 184 familial cases and 572 sporadic cases. The familial cases had a 2-fold higher prevalence of blood group B than did the sporadic cases, and the frequency of this blood group in non-affected relatives of cases was significantly reduced. Familial cases were about 2.7 times more likely to suffer from bilateral breast cancer than were the sporadic patients. These results support the presence of a genetic factor in the etiology of familial breast cancer.

    We report a 4-year retrospective study of 43 cases of breast cancer related to pregnancy and the post-natal period, corresponding to a 4.6% incidence in the breast cancers recorded during the same period. The mean age of our patients was 33 years. The most common reason for the consultation was the tumour. Inflammatory signs were present in 25% of cases and 80% of our patients had palpable under-arm adenopathies. 27% of cases were metastatic from the outset. The timing of treatment was the only parameter to be changed on the basis of age or the continuation of pregnancy or stage of the illness. Termination of pregnancy was carried out in only 2 cases. Recurrences occurred in 70% of cases and the survival median was 18 months. We noted that breast cancer during the perinatal period constitutes a poor prognosis, hence the importance of early diagnosis and care.

    Breast cancer is the most common malignancy affecting women worldwide. In Lebanon, a country of 4 million people, breast cancer is also the most prevalent type of cancer among Lebanese women. The purpose of this study was to gain a more in-depth understanding of the coping strategies espoused by Lebanese women with breast cancer. The study followed purposeful sampling and saturation principles in which 10 female participants diagnosed as having breast cancer were interviewed. Data were analyzed following a hermeneutical process as described by Diekelmann and Ironside (Encyclopedia of Nursing Research. 1998:50-68). Seven main themes and 1 constitutive pattern emerged from the study describing the Lebanese women's coping strategies with breast cancer. The negative stigma of cancer in the Lebanese culture, the role of women in the Lebanese families, and the embedded role of religion in Lebanese society are bases of the differences in the coping strategies of Lebanese women with breast cancer as compared to women with breast cancer from other cultures. These findings cannot be directly generalized, but they could act as a basis for further research on which to base a development of a framework for an approach to care that promotes coping processes in Lebanese women living with breast cancer. Nursing and medical staff need to have a better understanding of the individual coping strategies of each woman and its impact on the woman's well being; the creation of informal support group is indispensable in helping these women cope with their conditions.

    Evaluate concurrent Computer-Aided Detection (CAD) with Digital Breast Tomosynthesis (DBT) to determine impact on radiologist performance and reading time. The CAD system detects and extracts suspicious masses, architectural distortions and asymmetries from DBT planes that are blended into corresponding synthetic images to form CAD-enhanced synthetic images. Review of CAD-enhanced images and navigation to corresponding planes to confirm or dismiss potential lesions allows radiologists to more quickly review DBT planes. A retrospective, crossover study with and without CAD was conducted with six radiologists who read an enriched sample of 80 DBT cases including 23 malignant lesions in 21 women. Area Under the Receiver Operating Characteristic (ROC) Curve (AUC) compared the readings with and without CAD to determine the effect of CAD on overall interpretation performance. Sensitivity, specificity, recall rate and reading time were also assessed. Multi-reader, multi-case (MRMC) methods accounting for correlation and requiring correct lesion localization were used to analyze all endpoints. AUCs were based on a 0-100% probability of malignancy (POM) score. Sensitivity and specificity were based on BI-RADS scores, where 3 or higher was positive. Average AUC across readers without CAD was 0.854 (range: 0.785-0.891, 95% confidence interval (CI): 0.769,0.939) and 0.850 (range: 0.746-0.905, 95% CI: 0.751,0.949) with CAD (95% CI for difference: -0.046,0.039), demonstrating non-inferiority of AUC. Average reduction in reading time with CAD was 23.5% (95% CI: 7.0-37.0% improvement), from an average 48.2 (95% CI: 39.1,59.6) seconds without CAD to 39.1 (95% CI: 26.2,54.5) seconds with CAD. Per-patient sensitivity was the same with and without CAD (0.865; 95% CI for difference: -0.070,0.070), and there was a small 0.022 improvement (95% CI for difference: -0.046,0.089) in per-lesion sensitivity from 0.790 without CAD to 0.812 with CAD. A slight reduction in specificity with a -0

    Full Text Available INTRODUCTION: Cancer of breast is the second most common cause of cancer in women. In the present era, late marriage, late child birth, shorter period of breast feeding and nulliparity or low parity have contributed to increase in the number of cases. Fine needle aspiration cytology (FNAC is a useful method for initial evaluation and diagnosis of breast cancers and it has the ability of providing necessary prognostic predictive information. AIMS AND OBJECTIVES: The aim of the present study is to evaluate t he accuracy of FNAC of breast lesions with histopathological correlation. To study the cytomorphological features of palpable breast lumps. To study the various cytological patterns in aspirates from breast lesions and to classify them into non - neoplastic, benign and malignant lesions. To correlate the cytology findings with subsequent histopathological diagnosis wherever possible. To establish accuracy and efficacy of aspiration cytology as an early and preoperative diagnostic aid. To compare the statistic al analysis of present study with other contemporary studies.

    A woman presented for her postpartum examination alarmed about pink stains on her breast pads and on her infant's burp pads and diapers. The stains were also found in her breast pump and the infant's bottles. Out of concern, she stopped breastfeeding. The diagnosis was colonization of mother and infant with Serratia marcescens. They were managed conservatively without antibiotics. The mother was guided to restart breastfeeding. The infant resumed nursing and continued to thrive. © 2014 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Cross-sex hormone treatment of transsexual people may be associated with the induction and growth stimulation of hormone-related malignancies. We report here five cases of breast cancer, three in female-to-male (FtoM) transsexual subjects and two in male-to-female (MtoF) transsexual subjects. In the general population the incidence of breast cancer increases with age and with duration of exposure to sex hormones. This pattern was not recognised in these five transsexual subjects. Tumours occurred at a relatively young age (respectively, 48, 41, 41, 52 and 46 years old) and mostly after a relatively short span of time of cross-sex hormone treatment (9, 9-10 but in one after 30 years). Occurrence of breast cancer was rare. As has been reported earlier, breast tumours may occur in residual mammary tissue after breast ablation in FtoM transsexual people. For adequate treatment and decisions on further cross-sex hormone treatment it is important to have information on the staging and histology of the breast tumour (type, grade and receptor status), with an upcoming role for the androgen receptor status, especially in FtoM transsexual subjects with breast cancer who receive testosterone administration. This information should be taken into account when considering further cross-sex hormone treatment. © 2015 Blackwell Verlag GmbH.

    Full Text Available Objective. Despite studies suggesting that triple negative breast cancer is more often seen in women of African ancestry, we report here two cases of pregnancy associated triple negative breast cancer in Hispanic women. Cases. Case one is a 37-year-old female para 2-0-0-2, who presented with a left breast mass, at 19 weeks of gestation, the biopsy of which reported an invasive ductal carcinoma, found to be triple receptor negative. The patient underwent chemotherapy during the pregnancy and was delivered with a cesarean at 37 weeks for obstetric indication. After delivery, the patient completed her chemotherapy that was followed by radical mastectomy and radiotherapy. Case two is a 28-year-old female para 6-0-1-5, who presented while breast-feeding with signs and symptoms of mastitis, and an engorged and tender right breast, five months postpartum. However, the sonogram revealed a fluid filled cavity. Aspiration and cytology did not reflect an infection and were negative for malignancy. High suspicion and lack of improvement led to biopsy that identified an invasive ductal carcinoma, found to be triple negative. The patient underwent chemotherapy followed by modified radical mastectomy. Conclusions. Triple negative breast cancer, during pregnancy or postpartum, poses a unique challenge and requires a multidisciplinary team to optimize treatment for these women.

    Growing evidence suggests an association between active cigarette smoking and increased breast cancer risk. However, the weak magnitude of association and conflicting results have yielded uncertainty and it is unknown whether associations differ by breast cancer subtype. Using population-based case-control data from phases I and II of the Carolina Breast Cancer Study, we examined associations between self-reported measures of smoking and risk of Luminal and Basal-like breast cancers. We used logistic regression models to estimate case-control odds ratios (OR) and 95 % confidence intervals (CI). Ever smoking (current and former) was associated with a weakly increased risk of Luminal breast cancer (OR 1.12, 95 % CI 0.92-1.36) and was not associated with risk of Basal-like breast cancer (OR 0.96, 95 % CI 0.69-1.32). Similarly, smoking duration of more than 20 years was associated with increased risk of Luminal (OR 1.51, 95 % CI 1.19-1.93), but not Basal-like breast cancer (OR 0.90, 95 % CI 0.57-1.43). When stratified by race, elevated odds ratios between smoking and Luminal breast cancer risk were found among black women across multiple exposure measures (ever smoking, duration, and dose); conversely, among white women odds ratios were attenuated or null. Results from our study demonstrate a positive association between smoking and Luminal breast cancer risk, particularly among black women and women with long smoking histories. Addressing breast cancer heterogeneity in studies of smoking and breast cancer risk may elucidate associations masked in prior studies.

    To describe processes for the adoption of trastuzumab in four countries in the use of health technology assessment (HTA): Poland, Albania, Brazil and Colombia. Mixed methods were used for collection and triangulation of data. Data were examined following a conceptual framework connecting HTA process steps and key principles. Trastuzumab was generally assessed following well-structured HTA processes. Nonetheless, areas of improvement were detected in terms of transparency and inclusiveness, as well as in methods used. The extent to which different criteria influenced decisions was unclear. This study covers an area in which information may not always be available, and sets the example for emerging countries interested in HTA. Further studies to gain a better understanding on decision-making across settings are warranted.

    630 women patients of the Bad Trissl clinic were admitted in 1987/88 to a prospective study to find out whether scintiscanning, or radionuclide imaging, of the skeleton can be omitted completely or in part in the after care and follow-up of carcinoma of the breast. The initial criterion was a postoperative carcinoma of the breast without metastasizing in the skeleton at the time the study began or the patient was admitted to the study. Careful pain anamnesis was performed by means of prepared questions, and a detailed clinical examination conducted to detect any pain in the skeleton of the patient concerned. This was followed by whole body scintiscanning of the skeleton and complementary X-ray films, if necessary additional examinations. It was found that clinical findings and imaging methods agreed in 545 patients. In 55 cases a finding that was clinically suspicious of metastases or doubtful, could be refuted by both scintiscan and by X-ray, osseous metastasizing would have been overlooked without skeleton scintiscan in 14 patients only (2.2%), 11 of these 14 patients were high-risk patients (negative hormonal receptor status, axillary lymph node metastases). Hence, it will be sufficient to employ scintiscanning in the aftercare and follow-up of carcinoma of the breast on a risk-adapted basis provided this is preceded by careful pain analysis and clinical examination. Failure to detect metastasizing in the skeleton will then occur in only 3 of 630 patients (0.48%). In this manner 40% of scintiscans can be omitted in future. (orig.).

    African Journals Online (AJOL)

    Primary breast cancer when detected early can be treated by radical mastectomy alone. However, 20-30% of women treated as such later on, develop local or regional recurrence. This leads to an additional treatment with radiotherapy by the oncologist for the sake of the 20-30% of patients that may need it postoperatively.

    Fibroadenoma is the most common breast tumor in adolescent and young women. Fibroadenomas that consist of sclerosing adenosis, papillary apocrine metaplasia, epithelial calcifications, and/or cysts greater than 3 mm are considered as complex fibroadenoma. The relative risk of developing breast cancer in patients with complex fibroadenoma is increased, compared to women with noncomplex fibroadenoma. Extensive cystic degeneration in a fibroadenoma, so called "cystic fibroadenoma" is very rare. Herein, we present a case of such a lesion in a 43-year-old female who has been on follow-up for fibrocystic changes of the breast, and discuss both radiological and histopathologic differential diagnosis of this lesion with other cystic lesions of the breast, including cystic papilloma. The patient is free of disease after 17 months of clinical follow-up.

    Full Text Available According to the "World Cancer Research Fund" and the "American Institute of Cancer Research" (WCRF/AICR one in four cancer cases could be prevented through a healthy diet, weight control and physical activity.To explore the association between the WCRF/AICR recommendations and risk of breast cancer.During the period 2006 to 2011 we recruited 973 incident cases of breast cancer and 973 controls from 17 Spanish Regions. We constructed a score based on 9 of the WCRF/AICR recommendations for cancer prevention:: 1Maintain adequate body weight; 2Be physically active; 3Limit the intake of high density foods; 4Eat mostly plant foods; 5Limit the intake of animal foods; 6Limit alcohol intake; 7Limit salt and salt preserved food intake; 8Meet nutritional needs through diet; S1Breastfeed infants exclusively up to 6 months. We explored its association with BC by menopausal status and by intrinsic tumor subtypes (ER+/PR+ & HER2-; HER2+; ER&PR-&HER2- using conditional and multinomial logistic models respectively.Our results point to a linear association between the degree of noncompliance and breast cancer risk. Taking women who met 6 or more recommendations as reference, those meeting less than 3 showed a three-fold excess risk (OR=2.98(CI95%:1.59-5.59, especially for postmenopausal women (OR=3.60(CI95%:1.24;10.47 and ER+/PR+&HER2- (OR=3.60(CI95%:1.84;7.05 and HER2+ (OR=4.23(CI95%:1.66;10.78 tumors.

    Fractals are models of natural processes with many applications in medicine. The recent studies in medicine show that fractals can be applied for cancer detection and the description of pathological architecture of tumors. This fact is not surprising, as due to the irregular structure, cancerous cells can be interpreted as fractals. Inspired by Sierpinski carpet, we introduce a flexible parametric model of random carpets. Randomization is introduced by usage of binomial random variables. We provide an algorithm for estimation of parameters of the model and illustrate theoretical and practical issues in generation of Sierpinski gaskets and Hausdorff measure calculations. Stochastic geometry models can also serve as models for binary cancer images. Recently, a Boolean model was applied on the 200 images of mammary cancer tissue and 200 images of mastopathic tissue. Here, we describe the Quermass-interaction process, which can handle much more variations in the cancer data, and we apply it to the images. It was found out that mastopathic tissue deviates significantly stronger from Quermass-interaction process, which describes interactions among particles, than mammary cancer tissue does. The Quermass-interaction process serves as a model describing the tissue, which structure is broken to a certain level. However, random fractal model fits well for mastopathic tissue. We provide a novel discrimination method between mastopathic and mammary cancer tissue on the basis of complex wavelet-based self-similarity measure with classification rates more than 80%. Such similarity measure relates to Hurst exponent and fractional Brownian motions. The R package FractalParameterEstimation is developed and introduced in the paper.

    This anatomic study details the lymphatic drainage of the upper extremity (UE) and breast, as well as its course in the axilla and its relation to axillary reverse mapping. Two aspects important for breast cancer surgery were followed: connection between the lymphatics of the UE and breast, and the possible cause of lymphedema of the UE after sentinel node (SN) biopsy. Patent blue dye was injected bilaterally in 23 cadavers with no history of breast carcinoma to simultaneously visualize the lymphatics of the UE and breast. After visualization and dissection of the lymphatic vessels and nodes, a record of their routes was made. A scheme of superficial UE and breast lymphatics was constructed. After application of color contrast to the UE, 2-4 main afferent collectors were shown. As opposed to cranial and medial collectors, caudal collectors diverged from the axillary vein and entered the caudal axilla. In five (10.8%) cases, the caudal collector entered a node, which was considered to be the SN of the breast. In six (13%) cases, the SN of the breast and SNs of the UE were found in close proximity (up to 1.5 cm). Lymphatic drainage of the UE and breast are closely related in the caudal part of the axilla. SN groups for the UE and breast share connections in 24% of cases, which could explain lymphedema after surgery if damaged. Additional studies are needed to further improve our understanding of the lymphatic drainage of the UE and breast.

    The association of insomnia with subsequent breast cancer risk is largely unknown. Therefore, we assessed whether different symptoms of insomnia and their combination are associated with incident breast cancer in a large population-based study. In a prospective cohort study, 33,332 women were followed to monitor the occurrence of their first invasive breast cancer identified by the Cancer Registry of Norway. Insomnia symptoms including () nonrestorative sleep and () difficulty initiating and () maintaining sleep were self-reported using a study specific measure reflecting the current Diagnostic and Statistical Manual of Mental Disorders criteria. Hazard ratios and 95% confidence intervals were calculated using multiadjusted Cox proportional hazards models. A total of 862 incident breast cancer cases occurred during a mean follow-up of 14.7 years. No consistent association was observed between the individual insomnia symptoms and breast cancer risk. However, compared to women reporting no insomnia complaints, those who reported having all three aspects of insomnia simultaneously were at increased risk (hazard ratio, 2.38; 95% confidence interval = 1.11-5.09). Our results suggest that having only some aspects of insomnia may not predispose someone to breast cancer. In contrast, experiencing all insomnia symptoms simultaneously might confer considerable excess risk.

    Full Text Available Mutations in the p53 tumor suppressor gene and accumulation of its protein in breast tissue are thought to play a role in breast carcinogenesis. However, few studies have prospectively investigated the association of p53 immunopositivity and/or p53 alterations in women with benign breast disease in relation to the subsequent risk of invasive breast cancer. We carried out a case-control study nested within a large cohort of women biopsied for benign breast disease in order to address this question. After exclusions, 491 breast cancer cases and 471 controls were available for analysis. Unconditional logistic regression was used to estimate odds ratios (OR and 95% confidence intervals (95% CI. Neither p53 immunopositivity nor genetic alterations in p53 (either missense mutations or polymorphisms was associated with altered risk of subsequent breast cancer. However, the combination of both p53 immunopositivity and any p53 nucleotide change was associated with an approximate 5-fold nonsignificant increase in risk (adjusted OR 4.79, 95% CI 0.28–82.31 but the confidence intervals were extremely wide. Our findings raise the possibility that the combination of p53 protein accumulation and the presence of genetic alterations may identify a group at increased risk of breast cancer.

    PEGylated liposomal doxorubicin (PLD) has comparable efficacy and differing toxicity from conventional anthracyclines used to treat advanced breast cancer. This study compared disease-free survival and toxicity between PLD-based and conventional anthracycline-based regimens as adjuvant treatments for early-stage breast cancer. We analyzed disease-free survival (DFS) rates, and adverse events in 102 women with early-stage (I-IIIa) breast cancer who received adjuvant PLD-based chemotherapy from 2002 to 2008. Each patient was matched for age, stage at diagnosis, HER-2 expression and hormone therapy use to a patient treated with an epirubicin-based regimen. Fisher's exact and Pearson's chi-square tests were used for categorical data analysis. Kaplan-Meier analysis and Cox regression models were used to analyze DFS. DFS at 5 years was 81.3% for PLD-based regimen and 82.3% for epirubicin-based regimen. This difference was not significant (p = 0.939). Stage IIIa disease was associated with a shorter DFS in univariate analysis (p = 0.048). In multivariate analysis that controlled for adjuvant treatment, age at diagnosis, stage, HER-2 expression, type of surgery and hormone and radiation therapy, stage IIIa disease (P = 0.023) and lack of hormone therapy (P = 0.024) were each independently associated with shorter DFS. Adverse events were evaluated, and with the exception of hand-foot syndrome, more grade 3 and 4 toxicities occurred in patients who received epirubicin-based regimens than in those given PLD-based regimens. For patients with early-stage breast cancer who received PLD-based adjuvant chemotherapy, 5-year DFS was comparable and toxicity was acceptable, yet different from those of patients who received epirubicin-based regimens. © 2017 John Wiley & Sons Australia, Ltd.

    Breast cancer has emerged as the most prevalent cancer among women worldwide, including in Indonesia. The contribution of genes associated with high-risk breast-ovarian cancers, BRCA1 and BRCA2, in the Indonesian population is relatively unknown. We have characterized family history of patients with moderate- to high-risk of breast cancer predisposition in 26 unrelated cases from Indonesia for BRCA1/2 mutation analyses using direct sequencing. Known deleterious mutations were not found in either BRCA1 or BRCA2 genes. Seven variants in BRCA2 were documented in 10 of 26 patients (38%). All variants were categorized as unclassified (VUSs). Two synonymous variants, c.3623A>G and c.4035T>C, were found in 5 patients. One variant, c4600T>C, was found in a 38 year old woman with a family history of breast cancer. We have found 4 novel variants in BRCA2 gene including c.6718C>G, c.3281A>G, c.10176C>G, and c4490T>C in 4 unrelated patients, all of them having a positive family history of breast cancer. In accordance to other studies in Asian population, our study showed more frequent variants in BRCA2 compared to BRCA1. Further studies involving larger numbers of hereditary breast cancer patients are required to reveal contribution of BRCA1/2 mutations and/or other predisposing genes among familial breast cancer patients in Indonesia.

    Studies investigating the association between the methylenetetrahydrofolate reductase (MTHFR) gene 1298A>C polymorphism and the risk of breast cancer have reported inconsistent results. So, we performed this updated meta-analysis and tried to give a more precise estimation of association between MTHFR gene 1298A>C polymorphism and breast cancer susceptibility. Relevant studies published before 1 January 2016 were identified by searching PubMed and EMBASE. The strength of relationship between the MTHFR gene 1298A>C polymorphism and breast cancer susceptibility was assessed using odds ratio (OR) and corresponding 95 % confidence interval (95 % CI). The meta-analysis was performed using Stata 11.0 software. A total number of 38 case-control studies including 18,686 cases and 22,299 controls were identified. No association was found in five genetic models (dominant model: OR = 0.99, 95 % CI 0.99-1.00, P = 0.218; recessive model: OR = 1.00, 95 % CI 0.97-1.02, P = 0.880; homozygote genetic model: OR = 0.99, 95 % CI 0.98-1.01, P = 0.390; heterozygote genetic model: OR = 0.99, 95 % CI 0.97-1.00, P = 0.138; and allele contrast genetic model: OR = 0.99, 95 % CI 0.98-1.01) for MTHFR gene 1298 A>C polymorphism and breast cancer susceptibility. In the subgroup analysis stratified by source of control, decreased risk of breast cancer was found in studies with hospital-based controls in dominant model (OR = 0.98, 95 % CI 0.96-1.00, P = 0.037). Our meta-analysis suggested that there is no significant association between MTHFR gene 1298A>C polymorphism and breast cancer susceptibility for overall population.

    Digital breast tomosynthesis (DBT) is a recently developed system for three-dimensional imaging that offers the potential to reduce the false positives of mammography by preventing tissue overlap. Many qualitative evaluations of digital breast tomosynthesis were previously performed by using a phantom with an unrealistic model and with heterogeneous background and noise, which is not representative of real breasts. The purpose of the present work was to compare reconstruction algorithms for DBT by using various breast phantoms; validation was also performed by using patient images. DBT was performed by using a prototype unit that was optimized for very low exposures and rapid readout. Three algorithms were compared: a back-projection (BP) algorithm, a filtered BP (FBP) algorithm, and an iterative expectation maximization (EM) algorithm. To compare the algorithms, three types of breast phantoms (homogeneous background phantom, heterogeneous background phantom, and anthropomorphic breast phantom) were evaluated, and clinical images were also reconstructed by using the different reconstruction algorithms. The in-plane image quality was evaluated based on the line profile and the contrast-to-noise ratio (CNR), and out-of-plane artifacts were evaluated by means of the artifact spread function (ASF). Parenchymal texture features of contrast and homogeneity were computed based on reconstructed images of an anthropomorphic breast phantom. The clinical images were studied to validate the effect of reconstruction algorithms. The results showed that the CNRs of masses reconstructed by using the EM algorithm were slightly higher than those obtained by using the BP algorithm, whereas the FBP algorithm yielded much lower CNR due to its high fluctuations of background noise. The FBP algorithm provides the best conspicuity for larger calcifications by enhancing their contrast and sharpness more than the other algorithms; however, in the case of small-size and low

    Full Text Available Background. Breast cancer is the 5th leading cause of cancer death in Iranian women. This study analyzed 3010 women with breast cancer that had been referred to a cancer research center in Tehran between 1998 and 2014. Methods. In this retrospective study, we analyzed 3010 breast cancer cases with 32 clinical and paraclinical attributes. We checked the data quality rigorously and removed any invalid values or records. The method was data mining (problem definition, data preparation, data exploration, modeling, evaluation, and deployment. However, only the descriptive analyses’ results of the variables are presented in this article. To our knowledge, this is the most comprehensive study on breast cancer status in Iran. Results. A typical Iranian breast cancer patient has been a 40–50-year-old married woman with two children, who has a high school diploma and no history of abortion, smoking, or diabetes. Most patients were estrogen and progesterone receptor positive, human epidermal growth factor (HER negative, and P53 negative. Most cases were detected in stage 2 with intermediate grade. Conclusion. This study revealed original findings which can be used in national policymaking to find the best early detection method and improve the care quality and breast cancer prevention in Iran.

    Objective This study is about determination and eveluation of the breast cancer cases which were diagnosed during the early diagnosis and screening programs covering a three years of digital mammography images at the Near East University Hospital. Materials and Methods This study covers 2136 women patients who applied to the early diagnosis and screening program of the Near East University Hospital between July 2010 and July 2013. The mamographic images were re evaluated retrospectively according to ACR’s (The American College of Radiology) BİRADS (Breast Imaging Reporting and Data System). The mamographic results as required were correlated with breast ultrasound (US) and compared with the pathologic results of materials obtained by surgery or biopsy. The results were analyzed statistically in comparison with the literature data. Results The women who were screened aged between 34–73 years with a median of 53.5 (SD = 27.5). Suspected malignancy were evaluated in 54 patients, which 42 of them were diagnosed BIRADS 4 and 12 patients BIRADS 5 and 21 patients were correleted breast cancer based on histopathologic examination. 17 patients had the breast-conserving surgery and 4 patients were treated with mastectomy. Conclusion Breast cancers that are detected at early stages by breast cancer screening tests are more likely to be smaller and still confined to the breast resulting in more simple operations and more succesfull treatment. Promoting the breast cancer screening and registration programs in our country will help to control the desease at our region. PMID:28331685

    This breast cancer is one of the most important death causes in women. Among the more frequently medical treatment for advanced breast cancer is the mastectomy. This situation leads to silicone implants as an esthetic option. There have been cases in patients with implants where cancer was frequently detected, in which a conventional radiotherapy is required. In this work is presented a study of the probable adverse effects caused by the application of high power X-rays (6-10 MV) to the silicone implants and to the surrounding tissues. In the research carried out at the clinic, none Bolus effect was detected in patients with implants. Our results prescribe that in the case of patients with implants and frequent breast cancer, the removal of implants is not necessary due radiotherapy works directly in the damaged tissues. (Author)

    Full Text Available Lysyl oxidase (LOX is an extracellular enzyme essential for the covalent crosslinking of extracellular matrix proteins and may also have additional functions. LOX expression can be both up- and downregulated in cancer and is associated both with tumour suppression and metastasis progression. The G473A polymorphism (rs1800449 results in the Arg158Gln amino acid substitution in the LOX propeptide, compromises its tumour suppressive activity, and was associated with an increased breast cancer risk in a Chinese Han population. In the first hospital-based case-control study in European women, we aimed at investigating the association of LOX expression and the G473A polymorphism with breast cancer risk and survival in unselected and estrogen receptor (ER negative patients.The G473A polymorphism was genotyped in 386 breast cancer patients and 243 female controls. Moreover, LOX mRNA expression was quantified in the tumors of 105 patients by qRT-PCR. We found that the minor A-allele of this polymorphism is associated with a later age at breast cancer onset, a trend towards a decreased disease-free and metastasis-free survival, but not with an increased breast cancer risk. LOX mRNA expression was significantly elevated in tumours of patients older than 55 years, postmenopausal patients, estrogen receptor positive tumours, and p53 negative tumours, but was unaffected by G473A genotype in tumours and breast cancer cell lines. High LOX expression was associated with a poor disease-free and metastasis-free survival in ER negative but not ER positive patients. LOX expression was an independent prognostic parameter in multivariate analysis, whereas G473A genotype was not. A small, distinct subgroup of the ER negative patients was identified which exhibited a considerably elevated LOX expression and a very poor disease-free (p = 0.001 and metastasis-free survival (p = 0.0003.This newly identified ER negative/LOX high subgroup may be a suitable collective for

    Full Text Available Abstract Background Adnexal masses are not uncommon in patients with breast cancer. Breast cancer and ovarian malignancies are known to be associated. In patients with breast cancer and co-existing pleural effusions, ascites and adnexal masses, the probability of disseminated disease is high. Nevertheless, benign ovarian masses can mimic this clinical picture when they are associated with Meigs' syndrome making the work-up and management of these patients challenging. To our knowledge, there are no similar reports in the literature and therefore we present this case to highlight this entity. Case presentation A 56-year old woman presented with a 4 cm, grade 2, invasive ductal carcinoma of her left breast. Pre-treatment staging investigations showed a 13.5 cm mass in her left ovary, a small amount of ascites and a large right pleural effusion. Serum tumour markers showed a raised CA125 supporting the malignant nature of the ovarian mass. The cytology from the pleural effusion was indeterminate but thoracoscopic biopsy failed to show malignancy. The patient was strongly against mastectomy and she was commenced on neo-adjuvant Letrozole 2.5 mg daily with a view to perform breast conserving surgery. After a good response to the hormone manipulation, the patient had breast conserving surgery, axillary sampling and laparoscopic excision of the ovarian mass which was eventually found to be a benign ovarian fibroma. Conclusion Despite the high probability of disseminated malignancy when an ovarian mass associated with ascites if found in a patient with a breast cancer and pleural effusion, clinicians should be aware about rare benign syndromes, like Meigs', which may mimic a similar picture and mislead the diagnosis and management plan.

    Full Text Available BACKGROUND Ultrasound is a radiation free, readily available imaging modality that is routinely used for evaluation of breast. The patient usually are for routine checkup to nonspecific symptoms with few showing specific signs and symptoms. In this study, an attempt has been made to understand the role of ultrasound in diagnosing benign lesions with a drawback focused on early malignant lesion. Also, the differentiation of solid and cystic lesions can reduce biopsy. MATERIALS AND METHODS This study was done retrospectively evaluating 131 consecutive patients. The ultrasound study included evaluation of mainly female patients with few male cases. RESULTS Most common lesions were benign lesions. Among these benign lesions, fibroadenomas and fibrocystic disease were the commonest. However, there were no early malignant lesion seen in this study. CONCLUSION Breast ultrasound is choice of investigation in benign breast diseases. Also, such lesions can be easily followed up at primary level. However, there is a limited role in detecting early malignant lesions, which will require additional workup at a higher level especially in high-risk groups.

    Full Text Available Background: Glycogen-rich clear cell breast carcinoma is a rare histological breast cancer subtype. Its prognosis may vary depending on specific clinical and pathological characteristics such as low grade, strong positivity of estrogen receptor (ER expression and early diagnosis. Case Presentation: We present the case of a 53-year-old woman with a bleeding 10-cm-diameter mass in the left breast. The histological examination showed a poorly differentiated tumor with malignant cells characterized by abundant clear cytoplasm. The diagnosis of clear cell carcinoma was based on the histological characteristics of the tumor, and a nonmammary origin was initially ruled out. The tumor was triple negative [i.e. ER, progesterone receptor (PR and HER2 negative]. Four months after the initial locoregional treatment, the patient developed lung and distant lymph node metastases. Conclusions: Glycogen-rich clear cell carcinoma of the breast is a rare tumor. Early diagnosis, absence of lymph node metastases and ER/PR positivity are associated with a better prognosis, as in other common breast cancer subtypes.

  4. A Scary Onset of a Rare and Aggressive Type of Primary Breast Sarcoma: A Case Report

    2016-11-01

    Full Text Available Primary breast sarcoma, arising from connective tissue within the breast, is extremely rare, accounting for less than 1% of all primary breast malignancies and no more than 5% of all sarcomas. The rarity of this pathology limits most studies to case reports and small retrospective studies, which has led to a lack of consensus on the clinical management. We report a clinical case of a 52-year-old woman, perimenopausal, previously healthy, with regular breast surveillance, who presented with a large (>20 cm and rapidly expanding hypervascularized tumor of the left breast developed over 10 days, with a very thin preulcerative skin over the last 4 days. There was no systemic dissemination. The patient was submitted to total mastectomy and excision of axillary adenopathy. The tumor was diagnosed histologically as malignant phyllodes tumor associated with areas of high-grade sarcoma. Due to rapid growth and aggressive histological characteristics, adjuvant chemotherapy and radiotherapy were performed. There is a lot of evidence that tumors larger than 5 cm are associated with a poor prognosis. Despite the poor prognosis associated with this aggressive entity, the patient had no recurrence during 5 years of follow-up. We review the relevant literature about primary breast sarcomas.

    Adolescent girls are an important target group for breast cancer education and promoting breast awareness. However, research has not established schoolgirls' perceived importance of breast cancer education or explored factors that may impact engagement. This study aimed to identify schoolgirls' concerns about breast cancer, desire to know more and perceived importance of breast cancer education, and explored associations with demographic factors. Of 2089 schoolgirls (11-18 years) surveyed, 1958 completed all relevant breast cancer questions and demographic factors (ethnicity, school type, breast size, physical activity level and age). χ-Tests assessed associations between demographics, desire to know more and perceived importance of breast cancer. Overall, 44% of schoolgirls reported concerns about breast cancer, 72% wanted to know more and 77% rated the topic as extremely important. Breast size was not associated with wanting to know more about breast cancer. Schoolgirls who wanted to know more about breast cancer were White, from single-sex schools with boys at sixth form, more physically active and older. However, among other ethnic groups, school types and physical activity levels, the proportion of girls who wanted to know more about breast cancer was still high (≥61%). This study provides evidence of the need for breast cancer education for schoolgirls across all school types, irrespective of breast size or physical activity levels. The results highlight the need to be inclusive and engage schoolgirls from all ethnic groups and to promote breast awareness at a young age to ensure effective breast cancer education.

    Primary breast melanoma is extremely rare, and as such, there are no established radiologic findings in the literature. This report describes a case of primary malignant melanoma with mammography, ultrasonography, and magnetic resonance imaging findings. Our case study demonstrates a well-circumscribed heterogeneous rim-enhancing mass, with an internal cystic or necrotic portion seen using three modalities. Thus, although rare, this condition should be included in the differential diagnosis of a well-demarcated heterogeneous breast mass, and further pathological confirmation is needed.

    The purpose of this study was to compare in a retrospective observer study the diagnostic performance of full-field digital mammography (FFDM) with that of digital breast tomosynthesis. Eight experienced radiologists interpreted images from 125 selected examinations, 35 with verified findings of cancer and 90 with no finding of cancer. The four display conditions included FFDM alone, 11 low-dose projections, reconstructed digital breast tomosynthesis images, and a combined display mode of FFDM and digital breast tomosynthesis images. Observers rated examinations using the screening BI-RADS rating scale and the free-response receiver operating characteristic paradigm. Observer performance levels were measured as the proportion of examinations prompting recall of patients for further diagnostic evaluation. The results were presented in terms of true-positive fraction and false-positive fraction. Performance levels were compared among the acquisitions and reading modes. Time to view and interpret an examination also was evaluated. Use of the combination of digital breast tomosynthesis and FFDM was associated with 30% reduction in recall rate for cancer-free examinations that would have led to recall if FFDM had been used alone (p digital breast tomosynthesis alone also tended to reduce recall rates, an average of 10%, although the observed decrease was not statistically significant (p = 0.09 for the participating radiologists). There was no convincing evidence that use of digital breast tomosynthesis alone or in combination with FFDM results in a substantial improvement in sensitivity. Use of digital breast tomosynthesis for breast imaging may result in a substantial decrease in recall rate.

    Full Text Available This paper concerns a case of Malignant Fibrous Histiocytoma (MFH of the Breast in a 73-years-old woman. A lump was found in her right breast, measuring 1.7 cm in diameter. Surgical excision followed, and pathology revealed a highly atypical spindle cell tumor. Immunohistochemistry along the histological features, excluded the possibility of carcinoma, malignant phyllodes tumor, or another type of pure sarcoma. There was no history of previous irradiation in the region. MFH is among the rarest types of sarcoma of the breast, and most of the times behaves aggressively. Excision with wide, free-of-tumor margins is the most effective treatment, when feasible.

    Full Text Available Abstract Background Several studies have determined that dietary intake of B vitamins may be associated with breast cancer risk as a result of interactions between 5,10-methylenetetrahydrofolate reductase (MTHFR and methionine synthase (MTR in the one-carbon metabolism pathway. However, the association between B vitamin intake and breast cancer risk in Brazilian women in particular has not yet been investigated. Methods A case-control study was conducted in São Paulo, Brazil, with 458 age-matched pairs of Brazilian women. Energy-adjusted intakes of folate, vitamin B6, and vitamin B12 were derived from a validated Food Frequency Questionnaire (FFQ. Genotyping was completed for MTHFR A1298C and C677T, and MTR A2756G polymorphisms. A logistical regression model was used to calculate odds ratios (ORs and 95% confidence intervals (95% CIs. Results Neither dietary intake of folate, vitamin B6, or vitamin B12 nor MTHFR polymorphisms were independently associated with breast cancer risk. Analysis stratified by menopausal status showed a significant association between placement in the highest tertile of folate intake and risk of breast cancer in premenopausal women (OR = 2.17, 95% CI: 1.23–3.83; Ptrend = 0.010. The MTR 2756GG genotype was associated with a higher risk of breast cancer than the 2756AA genotype (OR = 1.99, 95% CI = 1.01–3.92; Ptrend = 0.801, and statistically significant interactions with regard to risk were observed between the MTHFR A1298C polymorphism and folate (P = 0.024 or vitamin B6 (P = 0.043, and between the MTHFR C677T polymorphism and folate (P = 0.043 or vitamin B12 (P = 0.022. Conclusion MTHFR polymorphisms and dietary intake of folate, vitamin B6, and vitamin B12 had no overall association with breast cancer risk. However, increased risk was observed in total women with the MTR 2756GG genotype and in premenopausal women with high folate intake. These findings, as well as significant interactions between MTHFR

    In tangential beam treatments accurate dose calculation of the absorbed dose in the build-up region is of major importance, in particular when the target has superficial extension close to the skin. In most analytical treatment planning systems (TPSs) calculations depend on the experimental measurements introduced by the user in which accuracy might be limited by the type of detector employed to perform them. To quantify the discrepancy between analytically calculated and delivered dose in the build-up region, near the skin of a patient, independent Monte Carlo (MC) simulations using the penelope code were performed. Dose distributions obtained with MC simulations were compared with those given by the Pencil Beam Convolution (PBC) algorithm and the Analytical Anisotropic Algorithm (AAA) implemented in the commercial TPS Eclipse. A cylindrical phantom was used to approximate the breast contour of a patient for MC simulations and the TPS. Calculations of the absorbed doses were performed for 6 and 18MV beams for four different angles of incidence: 15 degrees , 30 degrees , 45 degrees and 75 degrees and different field sizes: 3x3cm(2), 10x10cm(2) and 40x40cm(2). Absorbed doses along the phantom central axis were obtained with both the PBC algorithm and the AAA and compared to those estimated by the MC simulations. Additionally, a breast patient case was calculated with two opposed 6MV photon beams using all the aforementioned analytical and stochastic algorithms. For the 6MV photon beam in the phantom case, both the PBC algorithm and the AAA tend to underestimate the absorbed dose in the build-up region in comparison to MC results. These differences are clinically irrelevant and are included in a 1mm range. This tendency is also confirmed in the breast patient case. For the 18MV beam the PBC algorithm underestimates the absorbed dose with respect to the AAA. In comparison to MC simulations the PBC algorithm tends to underestimate the dose after the first 2-3mm of

    2017-04-01

    Pyoderma gangrenosum (PG) is a rare skin disorder of the neutrophilic dermatoses spectrum that can mimic wound infections in surgical patients. PG after breast surgery has been reported but in limited amounts in autologous breast reconstruction patients. We present the first case of PG after a delayed bilateral deep inferior epigastric perforator flap breast reconstruction in the setting of systemic disease along with a systematic review. PubMed, Ovid, and Web of Science were systematically searched to obtain cases of PG after autologous breast reconstruction. Sixty articles were identified but only 16 were relevant to this study. Systemic disease was present in 2 patients (13%). Wound onset occurred typically 5 days after surgery. Fever and/or leukocytosis was observed in 10 patients (63%). Wound cultures were positive in 2 patients (13%). Donor-site wounds were present in 9 patients (56%). Bilateral breast wounds were present in 67% of bilateral cases. Debridement was performed in 10 cases (63%). Skin graft or substitute was performed in 6 cases (38%). Resection of autologous flap was performed in 3 cases (19%). All patients were treated with systemic steroids (81%) and/or immunosuppressive medications (50%). Complete wound healing occurred by 4 months on average. If early ulcerative wounds develop at multiple sites after autologous breast reconstruction with worsening after debridement and antibiotic therapy, then PG should be considered. It is imperative that an early diagnosis and subsequent treatment with steroids and/or immunosuppressive medications be initiated so further surgical procedures, flap loss, and scarring can be minimized.

    Full Text Available BACKGROUND Breast cancer remains a global health problem with an increasing incidence. Proliferative breast diseases are recognised as one of the risk factors in the development of carcinoma. This study was undertaken to know the frequency of proliferative lesions and other lesions in association with breast carcinomas in mastectomy specimens. MATERIALS AND METHODS 100 cases of excised carcinoma breast sent to the Department of Pathology for a three-year period at tertiary care centre was thoroughly examined and changes adjacent to the tumour was recorded and tissue was subjected for histopathological examination and results tabulated. RESULTS Infiltrating duct cell carcinoma, Not Otherwise Specified (NOS type was present in 89% of cases. Among the associated lesions, nonproliferative lesions constituted 16%, proliferative breast disease without atypia 29%, proliferative breast disease with atypia 10% and others 45%. Fibrocystic disease constituted 14% of cases, epithelial hyperplasia 15%, sclerosing adenosis 12% and atypical ductal hyperplasia in 10% of cases. Other types of associated lesions were duct carcinoma in situ in 4 cases. CONCLUSION Proliferative lesions adjacent to carcinoma breast were seen in 39% of cases. Fibrocystic disease, epithelial hyperplasia, sclerosing adenosis and atypical ductal hyperplasia being the commonest lesions adjacent to carcinoma breast in the present study.

    Breast involvement by non-Hodgkin lymphomas is rare, and exceptional for T-cell lymphomas; we studied the morphologic, immunophenotypic, and clinical features of 11 patients with T-cell non-Hodgkin lymphomas involving the breast. Four cases fulfilled the definition criteria for primary breast lymphomas, 3 females and 1 male, with a median age of 51 years. One primary breast lymphomas was T-cell lymphoma unspecified, other was subcutaneous panniculitis-like T-cell lymphoma, and 2 cases were anaplastic large cell lymphomas. One of the anaplastic large cell lymphoma cases was found surrounding a silicone breast implant and presented as clinically as mastitis; whereas the other case occurred in a man. T-cell lymphoma secondarily involved the breast in 7 patients, all women and 1 bilateral, with a median age of 29 years. These secondary breast lymphomas occurred as part of widespread nodal or leukemic disease. Three patients had adult T-cell leukemia/lymphoma, including the patient with bilateral lesions, 3 others had precursor T-lymphoblastic lymphoma/leukemia, and the other presented with a peripheral-T-cell lymphoma nonotherwise specified type. Breast T-cell lymphomas are very infrequent and are morphologically and clinically heterogeneous. PMID:19318917

    Lourdes Alanis, MD, MPH

    2017-09-01

    Full Text Available Fibromatosis of the breast is a rare benign disease compromising <0.2% of all primary breast tumors. Although the chest wall is a common location, occurrences of implant-associated fibromatosis of the breast are extremely rare; only 33 cases have been reported. We present a case of a 42-year-old female who underwent breast augmentation with silicone breast implants, and 2 years later developed an aggressive implant-associated fibromatosis of the breast and chest wall. On imaging studies, the tumor mimicked breast carcinoma, and despite chemotherapy, the fibromatosis rapidly enlarged and was locally invasive requiring wide surgical excision. Unlike previously reported imaging findings, magnetic resonance imaging revealed an oval circumscribed mass with fringe-like internal architecture. We provide a review of the literature and discuss the imaging features of implant-associated fibromatosis of the breast.

    Gene panel testing for breast cancer susceptibility has become relatively cheap and accessible. However, the breast cancer risks associated with mutations in many genes included in these panels are unknown. We performed custom-designed targeted sequencing covering the coding exons of 17 known and putative breast cancer susceptibility genes in 660 non-BRCA1/2 women with familial breast cancer. Putative deleterious mutations were genotyped in relevant family members to assess co-segregation of each variant with disease. We used maximum likelihood models to estimate the breast cancer risks associated with mutations in each of the genes. We found 31 putative deleterious mutations in 7 known breast cancer susceptibility genes (TP53, PALB2, ATM, CHEK2, CDH1, PTEN and STK11) in 45 cases, and 22 potential deleterious mutations in 31 cases in 8 other genes (BARD1, BRIP1, MRE11, NBN, RAD50, RAD51C, RAD51D and CDK4). The relevant variants were then genotyped in 558 family members. Assuming a constant relative risk of breast cancer across age groups, only variants in CDH1, CHEK2, PALB2 and TP53 showed evidence of a significantly increased risk of breast cancer, with some supportive evidence that mutations in ATM confer moderate risk. Panel testing for these breast cancer families provided additional relevant clinical information for genes, but very large case-control sequencing studies and/or larger family-based studies will be needed to define the risks more accurately.

    Full Text Available Abstract Background Malignant peripheral nerve sheath tumor is a rare soft tissue sarcoma of ectomesenchymal origin. It is the malignant counterpart of benign soft tissue tumors like neurofibromas and schwannomas and may often follow them. Common sites include deeper soft tissues, usually in the proximity of a nerve trunk. Breast is an extremely rare location of this lesion and presentation as a breast lump in the absence of pain or previous benign neural tumor is even rarer. Case presentation A 38-year-old female presented with complaints of painless, hard breast lump for three months which was clinically suspected to be a ductal carcinoma with inconclusive fine needle aspiration cytology. Histopathology revealed a malignant spindle cell tumor which was confirmed to be malignant peripheral nerve sheath tumor on the basis of immunopositivity for vimentin, neurone specific enolase and S-100. Conclusion To the best of our knowledge only six such case reports have been published in literature. The differential diagnosis of malignant peripheral nerve sheath tumor should be considered by the clinician as well as the pathologists in the work-up of a breast neoplasm as treatment and prognosis of this rare malignancy is different.

    Full Text Available Breast cancer is the second most common cancer among females in rural areas of our country. It constitutes around 20-25% of all female cancers in India. ABO blood group has been observed to be associated with gastric and pancreatic cancer, but its association with breast cancer is unsure. AIMS & OBJECTIVES:1.To find any association between breast cancer and ABO blood group. 2. To know the frequency and risk of each blood group in relation to patients with breast cancer. This study was conducted in the Department of Surgery, Tirunelveli Medical College. Ethical committee approval was obtained.100 breast cancer cases were taken and 100 healthy women with no reports of breast cancer were taken as controls. Blood grouping was done by Standard Agglutination method. Association of ABO blood groups and breast cancer was found out with Odd Ratios (ORs with 95% Confidence Interval (CI. ABO blood group distribution among patients with breast cancer was as follows: Group A- 39%, Group O-31%, Group B- 26% and Group AB- 4% Among 100 healthy controls, ABO blood groups percentage was: Group O- 32%, Group A- 15 %, Group B- 46%, and Group AB- 7%. There is significant association between blood group A and breast Cancer since the p value was <0.05This study showed that there is strong association between ABO blood group system and female breast cancer and the highest risk for breast cancer was in blood group A and minimum in blood group AB.

    Although complete tumor resection is accepted as the best means to reduce recurrence, reoperations after lumpectomy are a common problem in breast cancer. The aim of this study was to assess the reoperation rates after primary breast conserving surgery in invasive breast cancer cases diagnosed in Catalonia, Spain, between 2005 and 2011 and to identify variations based on patient and tumour characteristics. Women with invasive incident breast cancer identified from the Patient's Hospital Discharge Database [174.0-174.9 codes of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) as the primary diagnosis] and receiving primary breast conserving surgery were included in the study and were followed up to 3 and 12 months by collecting information about repeat breast cancer surgery. Reoperation rates after primary breast conserving surgery decreased from 13.0 % in 2005 to 11.7 % in 2011 at 3 months and from 14.2 % in 2005 to 12.9 % in 2011 at 12 months' follow-up. While breast conservation reoperations saw a slight, non-significant increase in the same period (from 5.7 to 7.3 % at 3 months, and from 6.0 to 7.5 % at 12 months), there was a significant decrease in radical reoperation (from 7.3 to 4.4 % at 3 months and from 8.2 to 5.4 % at 12 months). Overall, additional breast surgeries decreased among younger women. Despite the rise of breast conserving surgery, reoperation rates following initial lumpectomy in Catalonia decreased by 10 % at 3 and 12 months' follow-up, remaining low and almost unchanged. Ultimately, there was also a significant decrease in mastectomies.

    Rosai-Dorfman Disease (RDD) is a rare disease that normally presents with bilateral cervical lymph node enlargement. Systemic symptoms of fever and weight loss may be present but patients are usually asymptomatic. This benign disease tends to regress on its own without treatment but there have been cases that required treatment with steroids or chemotherapeutic regimes. Extranodal disease in the breast is extremely rare, with only three cases identified in the male breast. The patient in this study presented with an asymptomatic right breast lump identified incidentally. After excisional biopsy, a diagnosis of RDD was confirmed on immunochemistry and histopathology.

    2003-12-01

    Full Text Available Abstract Background Mantle cell lymphoma (MCL is a rare variety of non-Hodgkin's lymphoma which originates from CD5+ B-cell population in the mantle zones of lymphoid follicles. Coexistence of such tumours in the axillary lymph nodes with invasive breast cancers without prior history of adjuvant chemotherapy or radiotherapy has not been previously reported in literature. Case report We report a rare case of breast cancer co-existing with stage I mantle cell lymphoma of the ipsilateral axillary lymph node detected fortuitously by population screening. Conclusion Though some studies have tried to prove breast carcinomas and lymphomas to share a common molecular or viral link, more research needs to be done to establish whether such a link truly exists.

    It has been reported that majority of cases of gigantomastia, also known as breast hypertrophy and macromastia, occur during either pregnancy or puberty. Gigantomastia is a rare disorder that does not have a clear etiology or well-established risk factors. We present a 26-year-old female patient who appeared to have pregnancy-associated gigantomastia recurrence, large accessory breast and, ectopic breast tissue at external genital three years after bilateral breast reduction surgery. The patient successively underwent bilateral mastectomy and vulvar tumor resection. Breast hypertrophy and progenital ectopic breast were pathologically confirmed. This the first case of gigantomastia reported worldwide.

    Full Text Available Abstract Introduction Invasive lobular carcinoma of the breast represents approximately 6.3% of mammary malignancies. Distant metastasis of invasive lobular carcinoma to the peritoneum or retroperitoneum has been reported fairly frequently. Case presentation We report the case of a 59-year-old Caucasian-Canadian woman with invasive lobular carcinoma of the breast presenting with retroperitoneal fibrosis and bilateral ureteral obstruction. Intra-operative pathology consultation did not reveal malignancy. The diagnosis, however, was confirmed on permanent sections by histological appearance in addition to immunohistochemistry. To the best of our knowledge, this is the first reported case of invasive lobular carcinoma of the breast presenting with retroperitoneal fibrosis. Conclusion In a case of unexplained ureteric obstruction and retroperitoneal fibrosis, more comprehensive physical examination and additional ancillary studies may be warranted to rule out malignancy as an underlying etiology. This case also emphasizes that intra-operative frozen section consultation cannot always be fully relied upon to exclude a malignancy as the etiology of retroperitoneal fibrosis. Moreover, in permanent histopathology sections, immunohistochemistry testing can be of value to rule out metastatic disease where the morphology is not salient. There is a need for a thorough physical examination of patients with retroperitoneal fibrosis, including the breast and gynecological organs.

    2009-01-01

    Introduction Serum vitamin D levels measured as 25-hydroxyvitamin D have been shown to be low in cancer patients, including breast cancer patients. However, the vitamin D status has yet to be studied in different breast cancer phenotypes: luminal A, luminal B, HER2+/ER-, and triple negative comprising the majority of basal-like. Case presentation Fifteen triple-negative breast cancer patients have presented to our medical oncology office in the last five years. Thirteen of these fifteen patients (87%) were found to be vitamin D deficient, defined as serum 25(OH)D less than 80 nmol/L, prior to initiation of adjuvant therapy. Ninety-one breast cancer patients from our office were classified as: luminal A (ER+ &/or PR+ and HER2-), luminal B (ER+ &/or PR+ and HER2+), HER2+/ER- (ER-, PR-, and HER2+), and triple-negative or basal-like (ER-, PR-, and HER2-). A normal mean was found from 78 volunteers. The breast cancer patients were found to be statistically different than the normal population. The triple-negative phenotype was found to be the most statistically different than the normal population. Conclusion The triple-negative breast cancer phenotype has the lowest average vitamin D level and the highest percentage of patients that are vitamin D deficient. These data suggests that low vitamin D levels are characteristic of the triple-negative phenotype. PMID:19830074

    Despite the knowledge of alternate lymphatic draining patterns of the breast, routine evaluation of the internal mammary lymph node basin is still not considered standard of care. The advent of microsurgical breast reconstruction using the internal mammary vessels as recipients, however, has allowed sampling of internal mammary lymph nodes with technical ease, thus revisiting their role in breast cancer management. In the present study, the authors reviewed their experience with this practice. A retrospective analysis of patients who underwent internal mammary lymph node biopsy at the time of autologous breast reconstruction using the internal mammary vessels between 2004 and 2012 was performed. Parameters of interest included patient age, timing of reconstruction (immediate versus delayed), disease stage, and pathologic findings of internal mammary lymph nodes. A total of 264 autologous breast reconstructions using the internal mammary vessels were performed in 204 patients with a median age of 44.5 years. The majority of reconstructions were immediate [n = 211 (79.9 percent)]. Seventy-two percent of patients had either stage I [72 patients (35.3 percent)] or stage II disease [75 patients (36.8 percent)]. Six patients were found to have internal mammary lymph node metastasis. Stage migration and alteration in adjuvant therapy occurred in all patients. Internal mammary lymph node sampling at the time of autologous breast reconstruction using the internal mammary system should become routine practice, as the morbidity associated with internal mammary lymph node harvest is low and the impact in cases of nodal involvement is quite substantial.

    When wrongly used, guideline-based clinical decision support systems (CDSSs) may generate inappropriate propositions that do not match the recommendations provided by clinical practice guidelines (CPGs). The user may decide to comply with or react to the CDSS, and her decision may finally comply or not with CPGs. OncoDoc2 is a guideline-based CDSS for breast cancer management. We collected 394 decisions made by multidisciplinary meeting physicians in three hospitals where the CDSS was evaluated. We observed a global CPG compliance of 86.8% and a global CDSS compliance of 75.4%. Non-CPG compliance was observed in case of a negative reactance to the CDSS, when users did not follow a correct CDSS proposition (8.6% of decisions). Because of errors in patient data entry, OncoDoc2 delivered non-recommended propositions in 21.3% of decisions, leading to compliances with CDSS and CPGs of respectively 21.4% and 65.5%, whereas both compliances exceeded 90% when CDSS advices included CPG recommendations. Automation bias, when users followed an incorrect CDSS proposition explained the remaining non-compliance with CPGs (4.6% of decisions). Securing the use of CDSSs is of major importance to warranty patient safety and benefit of their potential to improve care.

    While there is clear evidence for an association between later age at first live birth and increased breast cancer risk, associations with the timing of other reproductive events are less clear. As breast tissues undergo major structural and cellular changes during pregnancy, we examined associations between reproductive time events and intervals with breast cancer risk among parous women from the population-based Shanghai Breast Cancer Study (SBCS). Unconditional logistic regression was used to evaluate associations with breast cancer risk for 3,269 cases and 3,341 controls. In addition to later age at first live birth, later ages at first pregnancy and last pregnancy were significantly associated with increased breast cancer risk (p-trend = 0.002, 0.015, 0.008, respectively); longer intervals from menarche to first or last live birth were also associated with increased risk (p-trend associations for later age at first pregnancy or live birth and longer intervals from menarche to first or last live birth occurred among premenopausal women and ER+/PR+ breast cancers, whereas the association for later age at last pregnancy occurred among postmenopausal women and women with ER+/PR- or ER-/PR+ breast cancers. Because of the high correlation with other reproductive variables, models did not include adjustment for age at first live birth; when included, the significance of all associations was attenuated. These findings suggest that while reproductive time events and intervals play an important role in breast cancer etiology, contributions may differ by menopausal status and hormone receptor status of breast cancers. © 2013 UICC.

    Full Text Available Immunohistochemical markers are often used to classify breast cancer into subtypes that are biologically distinct and behave differently. The aim of this study was to estimate mortality for patients with the major subtypes of breast cancer as classified using five immunohistochemical markers, to investigate patterns of mortality over time, and to test for heterogeneity by subtype.We pooled data from more than 10,000 cases of invasive breast cancer from 12 studies that had collected information on hormone receptor status, human epidermal growth factor receptor-2 (HER2 status, and at least one basal marker (cytokeratin [CK]5/6 or epidermal growth factor receptor [EGFR] together with survival time data. Tumours were classified as luminal and nonluminal tumours according to hormone receptor expression. These two groups were further subdivided according to expression of HER2, and finally, the luminal and nonluminal HER2-negative tumours were categorised according to expression of basal markers. Changes in mortality rates over time differed by subtype. In women with luminal HER2-negative subtypes, mortality rates were constant over time, whereas mortality rates associated with the luminal HER2-positive and nonluminal subtypes tended to peak within 5 y of diagnosis and then decline over time. In the first 5 y after diagnosis the nonluminal tumours were associated with a poorer prognosis, but over longer follow-up times the prognosis was poorer in the luminal subtypes, with the worst prognosis at 15 y being in the luminal HER2-positive tumours. Basal marker expression distinguished the HER2-negative luminal and nonluminal tumours into different subtypes. These patterns were independent of any systemic adjuvant therapy.The six subtypes of breast cancer defined by expression of five markers show distinct behaviours with important differences in short term and long term prognosis. Application of these markers in the clinical setting could have the

    Full Text Available Background. Breast sarcomas are a heterogeneous group of breast neoplasms with a low incidence and a reserved prognosis. No treatment protocol has been yet established, a guideline similar to soft tissue sarcomas is used. Materials and Methods. Our study analyzed all the patients admitted with the diagnosis of malignant breast disease in two specialized centers on a five-year time frame. We compared long term results for the patients who underwent conservative treatment and mastectomy. Results. A total of 76 cases received surgical treatment with curative intent, 24 conservative procedures and 52 mastectomies. Incidence of local recurrence does not appear to be closely related to the type of surgical procedure. There were a number of five local recurrences for patients who received conservative treatment and 7 local recurrences where we used mastectomy. Kaplan-Meier analysis conducted shows no differences statistically significant (sig = 0.459 between the results of conservative treatment and mastectomy. Basically conservative surgery seems to get similar results, provided that R0 resection objective can be met. Conclusions. Treatment options are more limited for breast sarcomas than carcinomas, the role of surgery being more important to therapeutic success. The biological characteristic of the tumor including histological type and sub-type, play an important role in determining the results and the treatment should be tailored and adapted for each case.

    2017-09-26

    Arsenic is one of the heavy metals known to be a cause of cancer and many other serious human health problems. The International Agency for Research on Cancer (IARC), has classified arsenic as a Group 1 carcinogen. Studies were performed in different populations to investigate the association between arsenic and breast cancer and the present paper attempts to review these studies. Accessible electronic resources including, PubMed, Web of Knowledge, Science Direct and Scopus and Google Scholar were searched, with relevant phrases up to October 30, 2016. All articles were reviewed by two people separately and among them, original epidemiologic studies that investigated the association between breast cancer and exposure to arsenic were included. Eventually seven articles were selected from 126 retrieved articles. Although three studies (one case-control and two ecological) were not able to show a significant affect, others provide some evidence of a relation between arsenic and breast cancer in specific subgroups. Exposure to arsenic may increase the risk of breast cancer. The strength of this relation can vary due to regional and individual differences.

    Women with atypical hyperplasia (AH) on a benign breast biopsy specimen are at increased risk for the development of breast cancer. However, the relation between the type and extent of AH (atypical ductal hyperplasia [ADH] vs atypical lobular hyperplasia [ALH]) and the magnitude of the breast cancer risk is not well defined. A nested case-control study of benign breast disease and breast cancer risk was conducted. Women with breast cancer and prior benign breast biopsy findings (488 cases) were matched to women with prior benign breast biopsy findings who were free from breast cancer (1907 controls). Benign breast biopsy slides were reviewed and categorized as nonproliferative, proliferative without atypia, or AH (ADH or ALH). The number of foci of AH was also recorded. Among women with ADH, the interrelation between the extent of atypia and breast cancer risk was not significant (odds ratio [OR] for 1 or 2 foci, 3.5; 95% confidence interval [CI], 2.2-5.6; OR for ≥3 foci, 2.7; 95% CI, 1.4-5.1; P = .41). Similarly, although the risk with ALH was higher for those with ≥3 foci than for those with breast cancer risk. The lack of a significant dose-response relation between the extent and type of atypia and breast cancer risk suggests that it would be premature to use the extent of atypia to influence management decisions for women with ADH or ALH. © 2015 American Cancer Society.

    Extraskeletal myxoid chondrosarcoma is a unique and distinct clinicopathological entity in terms of its origin, morphology, and biologic behavior. Despite being a slow-growing tumor, it has a high rate of local recurrences and history of metastases to uncommon sites like the mandible, liver, retroperitoneum, right ventricle, pancreas, and central nervous system. Here, we report a very unique case of extraskeletal myxoid chondrosarcoma that metastasized to the breast, which itself is a very rare site for metastases. A 58-year-old woman presented with a large, firm, and tender soft-tissue mass (6.0×7.0 cm) underneath the sole of the left foot. A computerized tomography (CT) scan showed a heterogeneous lobulated mass in the plantar aspect of the forefoot, measuring 8.6×8.0×7.1 cm. Punch biopsies revealed histology consistent with extraskeletal myxoid chondrosarcoma. Metastatic work-up was negative. The mass was fully resected with left below-knee amputation. The histology of the resected mass was consistent with extraskeletal myxoid chondrosarcoma. A follow-up CT showed a new right breast nodule along with metastases to lung and bones. The results of the core needle biopsies of the right breast masses seen on mammogram were morphologically identical to extraskeletal myxoid chondrosarcoma. Although rare, metastases to the breast should be considered in the differential diagnosis of a breast mass. A close long-term follow-up is needed due to the unpredictable behavior of extraskeletal myxoid chondrosarcoma and the high frequency of local recurrences, metastases, and death due to disease.

    Gastric metastasis from primary breast cancer is a rare phenomenon that is more prevalent in the invasive lobular type of breast cancer. We describe a very rare case of occult invasive lobular cancer of the breast detected by the initial presentation of gastric metastasis in a patient without a history of breast cancer. A 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (FDG PET/CT) which showed increased FDG uptake in the stomach, abdominal mesentery and the right breast, and played pivotal roles in the detection of occult primary breast cancer and a diagnosis of gastric metastasis as an ancillary method for obtaining histological results and immunohistochemical stains.

    The potential mechanisms that link night-shift work with breast cancer have been extensively discussed. Exposure to light at night (LAN) depletes melatonin that has oncostatic and anti-estrogenic properties and may lead to a modified expression of estrogen receptor (ER) α. Here, we explored the association between shift work and breast cancer in subgroups of patients with ER-positive and -negative tumors. GENICA (Gene-ENvironment Interaction and breast CAncer) is a population-based case-control study on breast cancer with detailed information on shift work from 857 breast cancer cases and 892 controls. ER status was assessed by immunohistochemical staining. Associations between night-shift work and ER-positive and -negative breast cancer were analyzed with conditional logistic regression models, adjusted for potential confounders. ER status was assessed for 827 cases and was positive in 653 and negative in 174 breast tumors. Overall, 49 cases and 54 controls were "ever employed" in shift work including night shifts for ≥ 1 year. In total, "ever shift work" and "ever night work" were not associated with an elevated risk of ER-positive or -negative breast tumors. Night work for ≥ 20 years was associated with a significantly elevated risk of ER-negative breast cancer [odds ratio (OR) 4.73, 95% confidence interval (95% CI) 1.22-18.36]. Our case-control study suggests that long-term night-shift work is associated with an increased risk of ER-negative breast cancers. Further studies on histological subtypes and the analysis of other potentially relevant factors are crucial for discovering putative mechanisms.

    Full Text Available The term adenomyoepithelioma has been applied to a broad range of biphasic lesions composed of epithelial and myoepithelial cells. They show diverse morphologic patterns due to the admixture of the two components which may lead to a diagnosis of malignancy. We present a case of bilateral adenomyoepithelioma in a lactating woman who had a concomitant breast abscess. A 25-year-old lady presented with bilateral breast lumps since 2 years, with acute pain. With a clinical diagnosis of an abscess, superimposed on fibrocystic disease, drainage of abscess, and lumpectomy was performed. The clinicopathological features of this entity are discussed.

    We have studied 22 cases of mammary lipophyllodes tumors (LPT), analyzing their clinicopathologic features along with available follow-up. All cases were tested for cytokeratins, S100 protein, and MDM2, and in selected cases for estrogen receptor, smooth muscle actin, bcl2, desmin, and myogenin. Patients were women aged 21 to 69 years (average, 45 years), and LPT size ranged from 1.6 to 30 cm (average, 9.7 cm). Microscopically, LPT segregated as follows: atypical lipoma-like tumor/well-differentiated liposarcoma (ALT/WDL), 8 cases; myxoid, 6; and pleomorphic/poorly differentiated/round cell, 8, including a case of dedifferentiated liposarcoma. Immunohistochemistry studies showed focal positive staining for S100 and CD34 in most ALT/WDL, and desmin and myogenin in 2 cases with evidence of rhabdomyoblastic differentiation. MDM2 positivity was focally seen in 1 case. Follow-up was available in 8 cases. Multiple recurrent tumors were seen in 2 patients, and metastatic disease to the lung was seen in 2 patients. In 4 patients with a follow-up between 2 and 15 years there was no evidence of recurrent or metastatic disease. Patients with ALT/WDL (2/2) were alive with no evidence of disease; 2 of 4 patients with myxoid liposarcoma component experienced tumor recurrence, whereas pleomorphic liposarcoma LPT pursued a less favorable course although only 1 patient died of the condition. Absence of MDM2 reactivity in most cases seems not as meaningful as in fatty tumors of somatic soft parts. Copyright © 2015 Elsevier Inc. All rights reserved.

    Objectives Aircraft, road, and rail traffic noise can cause sleep disturbances. Since night work and shorter sleep durations have been linked to increased risks of breast cancer, we examined if 24-hour, or day- or night-time traffic noise exposure may also increase the risk of breast cancer. Methods To investigate the noise-related risks of breast cancer, the pseudonymized insurance records of three large statutory health companies (2005-2010) for women aged ≥40 years living in the region surrounding the Frankfurt international airport were analyzed with address-specific acoustic data representing aircraft, road, and rail-traffic noise. Noise exposure among women with incident breast cancer (N=6643) were compared with that of control subjects (N=471 596) using logistic regression and adjusting for age, hormone replacement therapy, education and occupation (only available for 27.9%), and a regional proportion of persons receiving long-term unemployment benefits as an ecological indicator of socioeconomic level. Analyses were also stratified according to estrogen receptor (ER) status. Results An increased odds ratio (OR) was observed for ER negative (ER-) tumors at 24-hour aircraft noise levels 55-59 dB [OR 55-59 dB 1.41, 95% confidence interval (CI) 1.04-1.90] but not for ER positive (ER+) breast cancers (OR 55-59 dB 0.95, 95% CI 0.75-1.20). Clear associations between road and rail traffic noise were not observed. Conclusions The results indicate increased aircraft noise may be an etiologic factor for ER- breast cancers. However, information regarding potential confounding factors was largely unattainable. Further research is required to understand how environmental noise may be involved in the pathogenesis of ER- breast cancers.

    Randy C. Miles, MD, MPH

    2017-12-01

    Full Text Available Accessory breast tissue results from failure of the embryologic mammary ridge, also known as the milk line, to involute. As a result, ectopic breast tissue can develop anywhere along this ridge, which extends from the axilla—the most common location—to the groin. Primary breast cancer in accessory breast tissue is uncommon but has been reported in multiple prior studies. We present a rare case of inflammatory breast cancer presenting in upper abdominal accessory breast tissue in women with a personal history of ipsilateral breast cancer, and highlight the challenges of both diagnosis and treatment of breast cancer in accessory breast tissue.

    Hereditary breast cancer syndrome was firstly associated with BRCA1 and BRCA2 genes the mutations of which confer high risk to develop breast and/or ovarian cancer. Double heterozygosity is a rare condition in which both BRCA1 and BRCA2 mutations are present in a family at the same time. In the current study, a family with double heterozygosity has been reported. Furthermore, for the first time a molecular analysis in both proband lineages, maternal and paternal, has been reported to understand the provenience of both germinal mutations.The case regards a woman who developed breast and ovarian cancer with liver metastasis which presented two mutations, each in the two genes, transmitted from her mother and her father, respectively. In this family all available members have been investigated. The concomitant presence of these peculiar mutations was never reported before suggesting a link with Caucasian population from Southern Italy.

    Several studies have suggested that post-traumatic stress disorder (PTSD) is related to adverse health outcomes. There are limited data on PTSD and cancer, which has a long latency period. We investigated the association between World War II (WWII)-related PTSD and subsequent breast cancer (BC) risk among Jewish WWII survivors and examined whether this association was modified by exposure to hunger during WWII. We compared 65 BC patients diagnosed in 2005 through 2010 to 200 population-based controls who were members of various organizations for Jewish WWII survivors in Israel. All participants were born in Europe, lived at least six months under Nazi rule during WWII, and immigrated to Israel after the war. We estimated PTSD using the PTSD Inventory and applied logistic regression models to estimate the association between WWII-related PTSD and BC, adjusting for potential confounders. We observed a linear association between WWII-related PTSD and BC risk. This association remained significant following adjustment for potential confounders, including obesity, alcohol consumption, smoking, age during WWII, hunger exposure during WWII, and total number of traumatic life events (OR = 2.89, 95% CI = 1.14-7.31). However, the level of hunger exposure during WWII modified this effect significantly. These findings suggest an independent association between WWII-related PTSD and subsequent BC risk in Jewish WWII survivors that is modified by hunger, a novel finding. Future research is needed to further explore these findings.

    Full Text Available Background: The Baby-Friendly Hospital Initiative was launched in 1989 by World Health Organization and the United Nations Children's Fund for the promotion of breastfeeding. This program was implemented in many departments of gynecology and obstetrics and resulted in reduced malnutrition, infection, morbidity and mortality in children. This program has introduced 10 specific steps to support successful breastfeeding. For instance, in the fourth step, skin-to-skin contact and breastfeeding are promoted since the time of birth, and in the fifth step, mothers are instructed on how to breastfeed or persist in breastfeeding. In these ten steps, mothers are trained in various fields. Methods: In this cross-sectional study, a standardized questionnaire was used to collect data at baby-friendly hospitals. To assess the difference between multiple nominal variables, variance analysis was performed, using SPSS version 17. Results: Based on the analysis, mothers' awareness of the benefits of breast milk and breastfeeding was 83% in a baby-friendly hospital. Also, their awareness of proper breastfeeding was estimated at 78.5%. In addition, mothers' knowledge about the frequency of breastfeeding was 70%. Conclusion: Given the role of Baby-Friendly Hospital Initiative in training mothers on the importance of breastfeeding and its persistence in future, careful monitoring of these hospitals, breastfeeding support services and breastfeeding training by midwives at healthcare centers are of great importance.

    Leiomyosarcoma of the breast is a rare neoplasm, primarily reported in older women. Only 44 cases have been reported in world literature and to the best of our knowledge, no case has been reported from India till date. We report a case of primary breast leiomyosarcoma in an adolescent girl who underwent a lumpectomy for rapidly increasing lump in the left breast. Here we report the histological findings and immunohistochemical profile of this entity, along with a review of existing literature. PMID:22953134

    Full Text Available Breast cancer is the most common carcinoma in women. Comprehensive therapy on breast cancer including surgical operation, chemotherapy, radiotherapy, endocrinotherapy, etc. could help, but still has serious side effect and resistance against anticancer drugs. Complementary and alternative medicine (CAM may avoid these problems, in which traditional Chinese medicine (TCM has been highlighted. In this section, to analyze the mechanism through which TCM act on breast cancer, we have built a virtual model consisting of the construction of database, oral bioavailability prediction, drug-likeness evaluation, target prediction, network construction. The 20 commonly employed herbs for the treatment of breast cancer were used as a database to carry out research. As a result, 150 ingredient compounds were screened out as active molecules for the herbs, with 33 target proteins predicted. Our analysis indicates that these herbs 1 takes a 'Jun-Chen-Zuo-Shi" as rule of prescription, 2 which function mainly through perturbing three pathways involving the epidermal growth factor receptor, estrogen receptor, and inflammatory pathways, to 3 display the breast cancer-related anti-estrogen, anti-inflammatory, regulation of cell metabolism and proliferation activities. To sum it up, by providing a novel in silico strategy for investigation of the botanical drugs, this work may be of some help for understanding the action mechanisms of herbal medicines and for discovery of new drugs from plants.

    Metabolome characterisation is a powerful tool in oncology. To obtain a valid description of the intracellular metabolome, two of the preparatory steps are crucial, namely washing and quenching. Washing must effectively remove the extracellular media components and quenching should stop the metabolic activities within the cell, without altering the membrane integrity of the cell. Therefore, it is important to evaluate the efficiency of the washing and quenching solvents. In this study, we employed two previously optimised protocols for simultaneous quenching and extraction, and investigated the effects of a number of washing steps/solvents and quenching solvent additives, on metabolite leakage from the adherent metastatic breast cancer cell line MDA-MB-231. We explored five washing protocols and five quenching protocols (including a control for each), and assessed for effectiveness by detecting ATP in the medium and cell morphology changes through scanning electron microscopy (SEM) analyses. Furthermore, we studied the overall recovery of eleven different metabolite classes using the GC-MS technique and compared the results with those obtained from the ATP assay and SEM analysis. Our data demonstrate that a single washing step with PBS and quenching with 60% methanol supplemented with 70 mM HEPES (-50 °C) results in minimum leakage of intracellular metabolites. Little or no interference of PBS (used in washing) and methanol/HEPES (used in quenching) on the subsequent GC-MS analysis step was noted. Together, these findings provide for the first time a systematic study into the washing and quenching steps of the metabolomics workflow for studying adherent mammalian cells, which we believe will improve reliability in the application of metabolomics technology to study adherent mammalian cell metabolism.

    Juvenile papillomatosis of the breast ("Swiss cheese disease'') is a benign localized proliferative condition of the breast which occurs almost exclusively in young adult women. Patients with this lesion often have a family history of breast carcinoma, but rarely carcinoma may coexist with the lesion at the time of diagnosis. We present a case of a young male with juvenile papillomatosis of the breast. The pathology and clinical management of this rare lesion is discussed.

    Full Text Available Abstract Background Primary non-Hodgkin lymphoma (NHL of the breast represents 0.04–0.5% of malignant lesions of the breast and accounts for 1.7–2.2% of extra-nodal NHL. Most primary cases are of B-cell phenotype and only rare cases are of T-cell phenotype. Anaplastic large cell lymphoma (ALCL is a rare T-cell lymphoma typically seen in children and young adults with the breast being one of the least common locations. There are a total of eleven cases of primary ALCL of the breast described in the literature. Eight of these cases occurred in proximity to breast implants, four in relation to silicone breast implant and three in relation to saline filled breast implant with three out of the eight implant related cases having previous history of breast cancer treated surgically. Adjuvant postoperative chemotherapy is given in only one case. Secondary hematological malignancies after breast cancer chemotherapy have been reported in literature. However in contrast to acute myeloid leukemia (AML, the association between lymphoma and administration of chemotherapy has never been clearly demonstrated. Case Presentation In this report we present a case of primary ALCL of the breast arising in reconstruction mamoplasty capsule of saline filled breast implant after radical mastectomy for infiltrating ductal carcinoma followed by postoperative chemotherapy twelve years ago. Conclusion Primary ALK negative ALCL arising at the site of saline filled breast implant is rare. It is still unclear whether chemotherapy and breast implantation increases risk of secondary hematological malignancies significantly. However, it is important to be aware of these complications and need for careful pathologic examination of tissue removed for implant related complications to make the correct diagnosis for further patient management and treatment. It is important to be aware of this entity at this site as it can be easily misdiagnosed on histologic grounds and to exclude

    551 patients were diagnosed with breast cancer in Tampere University Hospital district, Finland between 1977 and 1980. The number of follow-up visits during the first 5 years was 8248. The biological, physical, mental and social dimensions of breast cancer were measured by death, recurrence of disease, Karnofsky score, physical or mental symptoms, and sick leave. The prevalence rates of an event and the incidence rates of the appearance or disappearance of an event were used to determine the indicators for these different dimensions of breast cancer. The study was based on hospital case notes. Data on death, recurrence, sick leave and Karnofsky score were well recorded, but physical or mental symptoms were recorded infrequently. There was a 4-fold difference between the highest and lowest prevalence for the different dimensions, but the trends were similar by follow-up time. The variation was also large for the incidence rates but the trends differed with length of follow-up time. The biological, physical, mental and social consequences of breast cancer differ in magnitude and have different trends over time, indicating that breast cancer is a different disease depending on the dimension and on the indicator under consideration.

  11. Sequencing analysis of SLX4/FANCP gene in Italian familial breast cancer cases.

    Directory of Open Access Journals (Sweden)

    Irene Catucci

    Full Text Available Breast cancer can be caused by germline mutations in several genes that are responsible for different hereditary cancer syndromes. Some of the genes causing the Fanconi anemia (FA syndrome, such as BRCA2, BRIP1, PALB2, and RAD51C, are associated with high or moderate risk of developing breast cancer. Very recently, SLX4 has been established as a new FA gene raising the question of its implication in breast cancer risk. This study aimed at answering this question sequencing the entire coding region of SLX4 in 526 familial breast cancer cases from Italy. We found 81 different germline variants and none of these were clearly pathogenic. The statistical power of our sample size allows concluding that in Italy the frequency of carriers of truncating mutations of SLX4 may not exceed 0.6%. Our results indicate that testing for SLX4 germline mutations is unlikely to be relevant for the identification of individuals at risk of breast cancer, at least in the Italian population.

    Treatment with tamoxifen or chemotherapy reduces the risk of contralateral breast cancer (CBC). However, it is uncertain how long the protection lasts and whether the protective effect is modified by patient, tumor, or treatment characteristics. The population-based WECARE Study included 1521 cases with CBC and 2212 age- and year of first diagnosis-matched controls with unilateral breast cancer recruited during two phases in the USA, Canada, and Denmark. Women were diagnosed with a first breast cancer before age 55 years during 1985-2008. Abstraction of medical records provided detailed treatment information, while information on risk factors was obtained during telephone interviews. Risk ratios (RRs) and 95 % confidence intervals (CIs) for CBC were obtained from multivariable conditional logistic regression models. Compared with never users of tamoxifen, the RR of CBC was lower for current users of tamoxifen (RR = 0.73; 95 % CI = 0.55-0.97) and for past users within 3 years of last use (RR = 0.73; 95 % CI = 0.53-1.00). There was no evidence of an increased risk of estrogen receptor-negative CBC associated with ever use of tamoxifen or use for 4.5 or more years. Use of chemotherapy (ever versus never use) was associated with a significantly reduced RR of developing CBC 1-4 years (RR = 0.59; 95 % CI = 0.45-0.77) and 5-9 years (RR = 0.73; 95 % CI = 0.56-0.95) after first breast cancer diagnosis. RRs of CBC associated with tamoxifen or with chemotherapy use were independent of age, family history of breast cancer, body mass index and tumor characteristics of the first breast cancer with the exception that the RR of CBC was lower for lobular histology compared with other histologies. Our findings are consistent with previous studies showing that treatment with tamoxifen or chemotherapy is associated with a lower risk of CBC although the risk reduction appears to last for a limited time period after treatment is completed.

Primary SCNC of the breast is a rare tumor with less than 30 cases reported in the literature. Most cases are found in women. Another exceptional point is that human epidermal growth factor receptor-2 (Her-2 immunoreactivity was positive in our recent case, which differed to previous reports detailing SCNC in women. We have no evidence to demonstrate the differences between treatment and prognoses for males and females, because we do not have sufficient cases to undertake an evidence-based investigation. We provide this rare case history; review the literature on SCNC of the breast; and discuss detailed information regarding epidemiology, histogenesis, clinical and histologic diagnosis criteria, surgical and adjuvant treatment, and prognosis.Keywords: small-cell carcinoma, SMCC, neuroendocrine, male breast cancer, SCNC neoplasm

  17. Bilateral Giant Juvenile Fibroadenomas of Breasts:A Case Report

    2011-01-01

    Full Text Available Juvenile fibroadenoma constitutes only 4% of the total fibroadenomas. The incidence of giant juvenile fibroadenomas is found to be only 0.5% of all the fibroadenomas. Bilateral giant juvenile fibroadenomas are extremely rare, and only four cases have been reported in the literature. To the best of our knowledge, we are presenting the fifth case of bilateral giant juvenile fibroadenomas in a 12-year-old prepubertal girl. The diagnosis was made on fine-needle aspiration cytology which was confirmed on histopathology. In this paper, we present this rare case to illustrate the diagnosis and management of this tumour and to emphasize that these tumours are almost always benign and should be treated with breast-conserving surgery to provide a healthy physical and social life to the patient.

    Whether fat intake influences risk of developing more aggressive, lethal breast tumors is unknown. We evaluated intakes of total fat, specific types of fat, and cholesterol prior to diagnosis in relation to lethal breast cancer risk in 88,759 women in the Nurses' Health Study (NHS; 1980-2010) and 93,912 women in the Nurses' Health Study II (NHSII; 1991-2010). Diet was assessed every 4 years using a semi-quantitative food frequency questionnaire. Breast cancers were confirmed with pathology reports; deaths were confirmed by next of kin or the National Death Index. We defined lethal cases as women with invasive breast cancer who died of breast cancer. We pooled the cohorts and used multivariable Cox proportional hazards models. We identified 1,529 lethal breast cancer cases (1,279 in NHS and 250 in NHSII). Higher total fat intake was associated with a slightly lower lethal breast cancer risk (top vs. bottom quintile hazard ratio [HR] 0.85; 95 % CI 0.72, 1.01; p trend = 0.05). Specific types of fat were generally not associated with lethal breast cancer risk. For example, compared with those in the lowest quintile of saturated fat intake, those in the highest quintile had a HR of 0.98 (95 % CI 0.75, 1.26; p trend = 0.96). Among women diagnosed with breast cancer, pre-diagnosis fat intake was not associated with survival. Higher pre-diagnosis fat intake was not associated with greater risk of lethal breast cancer in these large prospective cohort studies, consistent with the weight of the evidence against a causal role for fat intake and breast cancer incidence.

    When standard therapies fail, clinical trials provide experimental treatment opportunities for patients with drug-resistant illnesses or terminal diseases. Clinical Trials can also provide free treatment and education for individuals who otherwise may not have access to such care. To find relevant clinical trials, patients often search online; however, they often encounter a significant barrier due to the large number of trials and in-effective indexing methods for reducing the trial search space. This study explores the feasibility of feature-based indexing, clustering, and search of clinical trials and informs designs to automate these processes. We decomposed 80 randomly selected stage III breast cancer clinical trials into a vector of eligibility features, which were organized into a hierarchy. We clustered trials based on their eligibility feature similarities. In a simulated search process, manually selected features were used to generate specific eligibility questions to filter trials iteratively. We extracted 1,437 distinct eligibility features and achieved an inter-rater agreement of 0.73 for feature extraction for 37 frequent features occurring in more than 20 trials. Using all the 1,437 features we stratified the 80 trials into six clusters containing trials recruiting similar patients by patient-characteristic features, five clusters by disease-characteristic features, and two clusters by mixed features. Most of the features were mapped to one or more Unified Medical Language System (UMLS) concepts, demonstrating the utility of named entity recognition prior to mapping with the UMLS for automatic feature extraction. It is feasible to develop feature-based indexing and clustering methods for clinical trials to identify trials with similar target populations and to improve trial search efficiency.

    Full Text Available BACKGROUND : In India it is observed that most of the patients of breast cancer clinically present in late stage due to their ignorance of disease despite so much advancement in its detection and management. Locally advanced breast cancer (LABC accounts for 30 - 35% of all cases of breast cancers in India. This study aims to evaluate C linical features, Investigations, various Treatment modalities and the Clinico - pathological correlation & outcome of various treatment modalities of LABC, with special emphasis on Neo - adjuvant chemotherapy (NACT in Indian setting. MATERIAL AND METHOD : This was a non - randomised prospective observational study. We analyzed 57 patients of LABC Stage IIIB & IIIC presenting at Government Medical College, Nagpur, Maharashtra, a tertiary care C entre from September 2012 to November 2014. RESULTS : Stage IIIB comprised 84.21% patients while remaining 15.79% were having Stage IIIC disease. Skin involvement was observed in 91.23% patients. 15.79% showed supraclavicular lymph node involvement. 32 patients received NACT (2 to 6 cycles. Out of these 32, complete clinical response (cCR was 12.5%, partial response (cPR was 68.75% and pathological CR (pCR was 6.25% with Total Objective response (cCR+cPR 81.25%. Feasibility of Breast Conserving Surgery (BCS was observed in 12.5% patients. 25 patients underwent primary surgery followed by adjuvant chemotherapy. Modified Radical Mastectomy was performed in 89.48% patients. CONCLUSIONS : With overall clinical response of 81.25%, n eoadjuvant chemotherapy is the best treatment option for patients with Locally Advanced Breast Cancer with added advantage of in vivo testing the sensitivity of chemotherapeutic agents, early management of micrometastasis and down staging the primary tumour with feasibility of BCS. Patients presenting LABC constitute a diverse group for whic h a variety of treatment modalities should be instituted with co o rdinated treatment planning among surgeons
